SUMMARY

RPA Data Wiz is a computer desktop application that allows users to customize summaries of Resource

Planning Act (RPA) Assessment forest information. Summary tables, graphs, and choropleth maps can be

produced with this software. A number of variables can be analyzed. Volumes for growing stock, live cull,

dead salvable, netgrowth, and mortality can be estimated. Acreage, biomass, and tree count estimates are

also available. Currently, removals are not available in this software. RPA Data Wiz is available in English

and metric versions. This software was developed using Microsoft Visual Basic 6.0 (SP5), Microsoft ADO,

Microsoft ADOX, Microsoft Windows Common Controls 6.0 (SP5), Microsoft Hierarchical FlexGrid

Control 6.0 (SP4), Microsoft Common Dialog Control 6.0, Microsoft Chart Control 6.0 (SP4 OLEDB),

ESRI MapObjects LT 2.0 (2000), a Microsoft Access 2000 database, several ESRI ArcView shapefiles, and a

number of other minor components.

The RPA Data Wiz Users Guide contains detailed information about querying Resource Planning Act (RPA)

Assessment forest data to produce summary tables, graphs, and maps. A number of variables can be

analyzed (appendix A, B, C). Volumes for growing stock, live cull, dead salvable, netgrowth, and mortality

can be estimated. Acreage, biomass, and tree count estimates are also available. Currently, removals are not

available in this software. RPA Data Wiz is available in English and metric versions. This software was

developed using Microsoft Visual Basic 6.0 (SP5), Microsoft ADO, Microsoft ADOX, Microsoft Windows

Common Controls 6.0 (SP5), Microsoft Hierarchical FlexGrid Control 6.0 (SP4), Microsoft Common

Dialog Control 6.0, Microsoft Chart Control 6.0 (SP4 OLEDB), ESRI MapObjects LT 2.0 (2000), Microsoft

Access 2000 databases, several ESRI ArcView shapefiles, and a number of other minor components. RPA

Data Wiz is available on CD by request from the North Central Research Station, St. Paul, MN (http://

www.ncrs.fs.fed.us/4801/tools-data/mapping-tools/rpa-data-wiz.asp).

This version of RPA Data Wiz uses the 2002 RPA Assessment. Most of the data comes from the Forest

Inventory and Analysis (FIA) program. (http://www.fia.fs.fed.us/, http://www.ncrs.fs.fed.us/4801/toolsdata/data; The Forest Inventory and Analysis Database: Database Description and Users Manual Version 1.0,

Miles et al. 2001). Other parts of the data come from lands administered by the National Forest System in

California, Colorado, Idaho, Nevada, Oregon, Washington, and Wyoming. RPA Data Wiz has no information for Hawaii or interior Alaska. In addition to the information provided in this users guide, a description

of the 2002 RPA data can be found in The 2002 RPA Plot Summary Database Users Manual Version 1.0 (Miles

and Vissage, In prep.).

The users guide begins with instructions for installing and removing RPA Data Wiz. Next, it provides some

general guidance for running RPA Data Wiz (Chapter 2). Chapters 3 through 5 cover the fine details of

running each part of the application. A tutorial chapter follows. You may wish to skip Chapters 3 through

5 and proceed to Chapter 6. Finally, several appendices define selection and output variables in RPA Data

Wiz.

Typographic Protocol

Most of the time this manual presents information in paragraph form. It tries to thoroughly cover important

aspects of each topic. Otherwise, bullets or numbered steps are used to present the information. When

reading this manual, keep in mind the following typographic protocol:

Example Description

Start \ Programs \ RPA Data Wiz Bold words should be chosen, typed, or

acknowledged.

A backslash between bold words indicates a

series of choices should be made.

multiple variable sums table Italicized words indicate a defined item or

term.

CTRL + S Capitalized letters usually indicate keyboard

keys. The + sign indicates multiple keys

should be pressed at the same time.

Tables and Graphs Capitalized words indicate the name of a

menu, dialog, button, or other object in

Windows or RPA Data Wiz.

“Installation” Words in quotation marks may be a reference to a specific section in the RPA Data

Wiz Users Guide.

System Requirements

Your computer must have one of the following operating systems:

• Windows 95

• Windows 98

• Windows NT 4.0 (need system administrator privileges to install)

• Windows 2000 (need system administrator privileges to install)

• Windows XP (need system administrator privileges to install)

Your computer must have the following:

• CD-ROM or DVD-ROM drive

• Microsoft Internet Explorer Version 5.0 or higher

• Total minimum of 848 MB of disk space for one version (1,030 MB for both versions)

• Minimum of 318 MB of hard disk space before installation (500 MB to install English and

metric versions)

• Minimum of 530 MB of hard disk to run RPA Data Wiz after installation

The following items are recommendations, but are not essential:

• Minimum of 200 MB of virtual memory

• Minimum of 512 MB of RAM

• Minimum of a Pentium III processor

• Minimum of a 14-inch computer monitor
3

As previously mentioned, there is an English and a metric version of RPA Data Wiz. Each employs a

different Microsoft Access database. The English version uses RPADb2002.mdb, which occupies approximately 183 MB; the metric version uses RPADb2002met.mdb, which occupies approximately 166 MB. The

installation package allows you to install one or both of these versions. In addition to the databases, other

support files are installed. If both versions are installed, the total package will require approximately 500

MB of storage space (approximately 318 MB of space for one database). Temporary files are created while

running RPA Data Wiz. Theoretically, the temporary files could occupy about 530 MB of additional space.

RPA Data Wiz will run more efficiently when sufficient virtual memory is allocated. We recommend that

the maximum amount of virtual memory be set to at least 200 MB. This amount is set in Control Panel \

System Properties \ Virtual Memory. We recommend at least 512 MB of RAM and a Pentium III or faster

processor. More RAM and faster processors will decrease the processing time of RPA Data Wiz. These are

only recommendations and RPA Data Wiz will run on slower computers. Remember that a slower computer could take hours to produce a complicated table using all the RPA data available for the United States

(there is a Stop button available).

Sometimes headings in the output tables, graphs, and maps can be quite long. On smaller computer

monitors (e.g., 12 or 14 inches), some headings can be cut off if you are using a coarse monitor resolution

(e.g., 640 X 480 or 800 X 600). If this is a problem, increase the resolution of the computer monitor.

1. Select Start \ Settings \ Control Panel.

2. Choose Display.

3. Select Settings in the Display Properties dialog.

4. Increase the resolution of the monitor to 1,024 X 768 or higher.

5. Select Apply and accept the settings.

6. Close the Display Properties dialog and the Control Panel form.

Installation

If you do not have Windows XP, you should read “Installation – Discussion and Notes” before executing

the following general installation instructions (focus on reading the notes that pertain to your operating

system). Follow these steps after you have covered the previous material or have determined that you have

Windows XP. Use system administrator privileges while loading in Windows NT 4.0, Windows 2000, or

Windows XP. Make sure programs like anti-virus software are not running. In general, insert the RPA Data

Wiz CD into your CD-ROM drive and execute the setup application, setup.exe. If the installation program

does not automatically start, then you will have to run setup.exe manually. Here is one way to run

setup.exe.

1. On the desktop, double-click My Computer.

2. Double-click the icon for the CD-ROM drive.

3. Double-click setup.exe (computer icon is usually associated with this file).

Here is a second way to run setup.exe.

1. Select Start \ Run.

2. In the Open input box, type the path to the setup.exe file on your CD-ROM drive plus

“setup.exe” (e.g., D:\setup.exe).

3. Click OK.

After the setup program starts, follow the directions.

1. Make sure other programs like anti-virus software are not running. Click OK to accept the

message.

2. Keep the default installation directory or click Change Directory to place RPA Data Wiz in an

alternate location. Remember that the directory for output from RPA Data Wiz will be in a

directory, temp, within the directory specified here. Click the computer icon to install RPA Data

Wiz in the specified directory.
4

3. Click the option indicating your choice of database(s). Click Done Selecting Databases(s).

4. Choose a group name or create a new one. We recommend using the default group name “RPA Data

Wiz.” If the default is chosen, then RPA Data Wiz will show up in Start \ Programs. We do not

recommend chosing Startup, because this will start RPA Data Wiz every time the computer boots up.

Click Continue.

5. The components will be installed.

If you are installing as system administrator, you may want to create a shortcut to RPA Data Wiz for other

login accounts.

1. Select Start \ Settings.

2. Choose Taskbar & Start Menu... \ Advanced \ Add.

3. Now Browse to the RPA Data Wiz application file, RPA_Data_Wiz.exe. The file is in the installation

directory you chose earlier, usually in C:\ProgramFiles\RPA Data Wiz\. Click RPA_Data_Wiz.exe.

4. Click Next and the location where you wish the shortcut to appear. Click Next \ Finish. Finally,

click OK on the Taskbar and Start Menu Properties dialog.

Installation – Discussion and Notes

Either Microsoft Windows 95, Windows 98, Windows NT 4.0, Windows 2000, or Windows XP with the

appropriate updates and Microsoft Internet Explorer version 5.0 or higher are required to run RPA Data Wiz.

RPA Data Wiz is not supported in Windows 3.1, Windows NT 3.51, or older systems. Windows ME is not

supported. Most computers will have the necessary components to install and run this application. However,

there is wide variability among the Windows operating systems present on computers. Some users will have

to install updates to their operating systems. The setup program installs Microsoft Data Access Components

(MDAC) 2.5 SP2 (2.52.6019.2) on Windows 95, 98, and NT 4.0. The setup program cannot install MDAC on

Windows 2000 machines. Windows 2000 service pack 2 or newer is required to install MDAC on a Windows

2000 operating system. Windows XP already has the necessary MDAC. MDAC includes Microsoft Jet 4.0

(SP5). The MDAC End-User License Agreement (EULA) is found on the installation CD in the

Windows_Support directory. The setup program installs other Microsoft support files, MapObjects LT 2.0

(ESRI 2000) components, Microsoft Access database files, map layers as ArcView shapefiles, the RPA Data Wiz

application file, and supporting documentation. In rare instances, the installation process may require a

reboot after some system files are updated. If necessary, the setup program will indicate the required reboot. If

a reboot is required to update system files, then the RPA Data Wiz setup program must be run a second time.

The following list contains information critical to installing RPA Data Wiz in specific Windows operating

systems:

Microsoft Windows 95

The Distributed Component Object Model (DCOM) must be installed on Windows 95 operating systems. A

number of applications (e.g., Microsoft Internet Explorer 4.01 and 5.0) install DCOM automatically, so it may

be present on your machine. DCOM can be detected on your system if a search of the registry keys contains

{bdc67890-4fc0-11d0-a805-00aa006d2eaf4}. This does not mean you have the latest version of DCOM. The

latest version at the time of this writing is DCOM95 version 1.3. This can be found on the installation CD in

the Windows_Support directory of this application as dcom95.exe. The DCOM95 version 1.3 EULA can also

be found on the CD. The most recent version of DCOM for Windows 95 may be found at http://

www.microsoft.com/com/resources/downloads.asp. We recommend you do not work with the registry. If

DCOM is not installed, the RPA Data Wiz application will issue an error and fail to run. This is the easiest way

to determine if DCOM is not installed. If the RPA Data Wiz installation fails, then install DCOM (copy

dcom95.exe from the Windows_Support\dcom95 directory of the installation CD to your machine and

execute the file). You will have to reinstall RPA Data Wiz, but first uninstall the previous RPA Data Wiz

installation (see “Uninstalling RPA Data Wiz” later in this chapter).

The most recent version of

DCOM for Windows 95 may be

found at http://

www.microsoft.com/com/

resources/downloads.asp.
5

MDAC 2.5 service pack 2 installs with the RPA Data Wiz setup program. MDAC 2.5 service pack 2 will not

install if a newer version of MDAC exists on your machine. Although it’s unlikely, a previous user could

have installed a newer version of MDAC like 2.6 or 2.7. These versions do not come with the Jet 4.0

components required by RPA Data Wiz. More than likely, some other program has already installed the Jet

components on your machine. However, if they do not exist, then RPA Data Wiz will not connect to the

required Microsoft Access database. In this case, RPA Data Wiz will give errors indicating that it cannot

connect to the database. You will have to install Jet 4.0 service pack 3.0 (http://www.microsoft.com/data/

download.htm) at a minimum. Jet 4.0 service pack 3.0 is also available on the CD in the Windows_Support

directory. After installing Jet 4.0 service pack 3.0, you have the option to upgrade to the latest service pack.

Microsoft Windows 98

The Distributed Component Object Model (DCOM) must be installed on Windows 98 operating systems.

DCOM comes on Windows 98 Second Edition. A number of applications (e.g., Microsoft Internet Explorer

5.0, Microsoft Visual Studio 6.0, Microsoft Office 2000) install DCOM automatically, so it may be present

on your machine. DCOM can be detected on your system if a search of the registry keys contains

{bdc67890-4fc0-11d0-a805-00aa006d2eaf4}. This does not mean you have the latest version of DCOM.

The latest version at the time of this writing is DCOM98 version 1.3. The most recent version of DCOM for

Windows 98 may be found at http://www.microsoft.com/com/resources/downloads.asp. Microsoft does not

allow redistribution of DCOM98 so it is not available on the installation CD. We recommend you do not

work with the registry. If DCOM is not installed, the RPA Data Wiz application will issue an error and fail

to run. This is the easiest way to determine if DCOM is not installed. If the RPA Data Wiz installation fails,

then install DCOM (double-click the DCOM file). You will have to reinstall RPA Data Wiz, but first

uninstall the previous RPA Data Wiz installation (see “Uninstalling RPA Data Wiz” later in this chapter).

MDAC 2.5 service pack 2 installs with the RPA Data Wiz setup program. MDAC 2.5 service pack 2 will not

install if a newer version of MDAC exists on your machine. Although it’s unlikely, a previous user could

have installed a newer version of MDAC like 2.6 or 2.7. These versions do not come with the Jet 4.0

components required by RPA Data Wiz. More than likely, some other program has already installed the Jet

components on your machine. However, if they do not exist, then the RPA Data Wiz will not be able to

connect the Microsoft Access database. In this case, RPA Data Wiz will give errors indicating that it cannot

connect to the database. You will have to install Jet 4.0 service pack 3.0 (http://www.microsoft.com/data/

download.htm) at a minimum. Jet 4.0 service pack 3.0 is available on the installation CD in the

Windows_Support directory. After installing Jet 4.0 service pack 3.0, you have the option to upgrade to the

latest service pack.

Microsoft Windows NT 4.0

DCOM is already installed on Windows NT 4.0. Run the RPA Data Wiz setup program. If system files are

updated, then a reboot and a second run of the setup program will be required.

MDAC 2.5 service pack 2 installs with the RPA Data Wiz setup program. MDAC 2.5 service pack 2 will not

install if a newer version of MDAC exists on your machine. Although it’s unlikely, a previous user could

have installed a newer version of MDAC like 2.6 or 2.7. These versions do not come with the Jet 4.0

components required by RPA Data Wiz. More than likely, some other program has already installed the Jet

components on your machine. However, if they do not exist, then RPA Data Wiz will not connect to the

required Microsoft Access database. In this case, RPA Data Wiz will give errors indicating that it cannot

connect to the database. You will have to install Jet 4.0 service pack 3.0 (http://www.microsoft.com/data/

download.htm) at a minimum. Jet 4.0 service pack 3.0 is also available on the installation CD in the

Windows_Support directory. After installing Jet 4.0 service pack 3.0, you have the option to upgrade to the

latest service pack.

The most recent version of DCOM

for Windows 98 may be found at

http://www.microsoft.com/com/

resources/downloads.asp.
6

Microsoft Windows 2000

DCOM is already installed on Windows 2000. The Windows 2000 operating system must have service pack 2

or newer. Service packs may be found at http://www.microsoft.com/windows2000/downloads/servicepacks/

default.asp. Check the service pack on your system in My Computer \ Properties. Click the General tab and

look under System. After verifying that service pack 2 or newer is installed, run the RPA Data Wiz setup

program. System files cannot be updated on this operating system without installing service packs or other

Microsoft software updates. Run the RPA Data Wiz setup program. If you try installing and get a message

indicating that some of your system files are out of date, then you do not have service pack 2 or newer

installed.

Microsoft Windows XP

Windows XP has the necessary system files for the RPA Data Wiz setup program. Run the RPA Data Wiz setup

program.

Uninstalling RPA Data Wiz

You may want to uninstall RPA Data Wiz. If you run into trouble and RPA Data Wiz does not install correctly,

the safest thing to do is uninstall the application. RPA Data Wiz can be installed again later. When uninstalling

RPA Data Wiz we recommend you do not remove shared files. Here are the steps for uninstalling RPA Data

Wiz.

1. Select Start \ Settings \ Control Panel.

2. Choose Add/Remove Programs.

3. Look for and select RPA Data Wiz.

4. Select Change/Remove.

5. Select Yes to remove the application.

6. If you are asked to remove shared files, we highly recommend you do not remove them.

References

A number of references are associated with map layers in RPA Data Wiz. Some of the map layers were created

by manipulating other original map layers. The references directory of the installation CD has the references

for the original map layers. See readme.txt in the references directory for further information. The RPA Data

Wiz application directory (usually C:\Program Files\RPA Data Wiz\) has the reference information or metadata

for each of the final map layers used in RPA Data Wiz. These files have “met” extensions and can be read in a

text editor. The references directory on the installation CD also has the original references for the rural urban

continuum and Baileys’ ecological subregion codes.

Chapter 2

Getting Started with RPA Data Wiz

RPA Data Wiz allows users to create tables, graphs, and maps of the forest information from the 2002 RPA

Assessment database without having to know the structure of the database and without having to know

computer programming or Structured Query Language (SQL is a standard ANSI / NCITS language for

querying and manipulating databases). Pointing and clicking in the graphical user interface works to

achieve most results. A user performs the following basic steps:

1. Pick one or more RPA subregions to work in. All RPA plot information is initially chosen for the

subregions you pick.

2. Narrow your selection of RPA plot information by picking variables and their respective values of

interest. For example, you could choose only to work with oak forest types on timberland.

3. Make summary tables, graphs, and maps on the resulting information.

4. Save your tables, graphs, and maps in a number of formats to use in other applications.

5. Repeatedly add to or select from your existing RPA plot information and create more output.

Answering Questions

You can answer many questions with RPA Data Wiz—a small sample is included below. Not all of these

questions are answered directly in this users guide, but the guide presents methods that allow you to

answer these questions and more. In the examples below, geographic units can be RPA assessment regions

or subregions, States, counties, Baileys’ Ecosections, 107th or 108th Congressional Districts, USGS Hydrological Accounting Units, or U.S. National Forest System lands. Volumes can be for growing stock, live

cull, dead salvable, netgrowth, or mortality.

• What is the biomass, volume, or number of trees on a per area basis?

• What is the ratio of mortality to netgrowth?

• What is the ratio of softwood to hardwood?

• What is the ratio of large trees to all trees?

• What is the ratio of forest land or timberland to all land by geographic unit?

• What is the ratio of National Forest System timberland to private timberland (derive

indirectly using output from RPA Data Wiz in a spreadsheet)?

• What is the ratio of productive reserved forest land to productive nonreserved forest

land by forest type and age class (derive indirectly using output from RPA Data Wiz in a

spreadsheet)?

• What geographic units have overstocked forest stands and how much biomass is

present in these areas (may indicate fire hazard)?

• What is the volume, biomass, or number of trees in highly productive black walnut

stands?

• What is the volume, biomass, or number of trees by owner and stand-diameter class?

• What is the volume, biomass, or number of trees by age and stand-size class?

• What is the volume, biomass, or number of trees in planted versus natural forest stands?

• How much stand conversion, clearcutting, or other type of treatment has occurred in

each geographic unit?

• What is the volume, biomass, or number of trees associated with counties that have

various levels of rural/urban continuums (levels of metropolitan or urban development)?

• What geographic units have potentially favorable habitat for a particular animal species

of interest?
8

Important Points

Before covering specific methods and examples of output, there are several important points to remember

when using RPA Data Wiz.

• Many times throughout this application, multiple selections are allowed. Unless noted

otherwise, hold SHIFT and click over a range of choices or hold CTRL and click on

multiple individual choices. One of these noted exceptions occurs when creating tables and

picking grouping variables.

• Remember that choices in menus or dialogs are only enabled or available when they appear

in text that contrasts with the background (e.g., black text on the gray menu).

• The abbreviations “SW” and “HW” represent softwood and hardwood respectively

throughout RPA Data Wiz.

• “AEF” occurs in the output tables and represents area (appendices B and C).

• Make sure your form sizes are maximized to see the graphs well (click on the box in upper

right-hand corner of each form to maximize the size).

• Since the data were acquired from a number of sources using various sampling techniques,

there is no easy way to present sampling errors. The number of plots or records associated

with a query is the only measure of accuracy provided. Most of the data in the 2002 RPA

Assessment do come from the FIA program. A description of the FIA sampling and

accuracy standards can be found in The Forest Inventory and Analysis Database: Database

Description and Users Manual Version 1.0 (Miles et al. 2001).

• Area is the only attribute information that can be output for nonforest and water plots.

Otherwise, all the output information in RPA Data Wiz is associated with some type of

forest land. Therefore, you will usually limit your selections to some type of forest land (see

Land Cover Class and Forested Land Code in appendix A).

• Time series analysis is not part of RPA Data Wiz. The database is a “snapshot” of the most

up-to-date information. A small amount of this latest information is decades old. Source

Date (appendix A) indicates the year of the information.

• Information on individual tree species is not part of RPA Data Wiz. Forest Type Group and

Local Forest Type are available (appendix A).

• Number of trees and board-foot volume (appendix B) are only available for timberland (see

Forested Land Code in appendix A). In addition, board-foot volume is only available in the

English version of RPA Data Wiz.

• Finally, the structure of this application is very autonomous, allowing users a great degree

of freedom to pick specific RPA information and present it in many ways. Take care to

make selections and create output in ways that make sense. As an aide, we recommend

looking over the definitions of the selection and output variables in the appendices.

Starting RPA Data Wiz

There are a number of ways to start RPA Data Wiz, depending upon how you installed the application. If the

defaults were selected during installation, then RPA Data Wiz will show up in Start \ Programs. Select Start \

Programs \ RPA Data Wiz. You may have created a shortcut to the application. If this is the case, doubleclick the shortcut. Otherwise, go to the installation directory and double-click the RPA Data Wiz application

file, RPA_Data_Wiz.exe.

After starting the application, a splash screen will appear. Click in the gray area of this screen to proceed. If

you installed the English and metric databases, then you will have to decide whether to work with the English

or metric version of RPA Data Wiz.

Help

Select Help \ RPA Data Wiz Info to display reference information on RPA Data Wiz. Select Help \ Help

and you will be referred to the RPA Data Wiz Users Guide. In this version, there is no help section built

into the program. However, tool tips appear for a number of objects in RPA Data Wiz. Momentarily place

the cursor over an object to see if a tool tip is available. Most menus do not have tool tips. Just click on the

menu to see what is available. Any future updates to RPA Data Wiz will be located at http://

Working with Sessions

New Session

You can start a new session in many different stages throughout the application. Right after starting RPA Data

Wiz, you have to start a new session. Start a new session by clicking Session \ New Session.

After creating a new session, you have to choose one or more RPA subregions. After making your choice, click

Done Selecting RPA Subregion(s).
11

Next, the RPA Variable Selection dialog appears. Select a single variable. The Select Field Value(s) dialog

appears with all the available values for the previously chosen variable. Choose any number of these values

for the variable. Click Done Selecting Field Value(s). Repeat this process as many times as necessary to

reduce the selection of database records. Normally, you would include a selection here for some type of

forest land (Forest Land as the value for Land Cover Class or a specific forest land type for Forested Land

Code). Area is the only output variable associated with nonforest and water. Press Done Selecting to keep

the selection criteria or choose Skip Selecting – Use All Current Records to use all the current records in

future analyses.
12

If desired, choose Query History to show a simplified version of the selection code. Field names and codes

appear as they are in the RPA Data Wiz database. Note that sometimes the length of the selection queries can

become longer than is allowed. If this is the case, the query will fail and a new query will have to be chosen

with fewer selection criteria. Some field value code definitions are listed in Query History; however, all of

them are listed in appendix A.
13

Select from Existing Selection

After you have completed creating a new session, you can go back and narrow that selection further. Using

the existing records selected from New Session, click Session \ Select from Existing Selection to allow

further reselection of records with the RPA Variable Selection and Select Field Value(s) dialogs as previously

described. Any time Select from Existing Selection is enabled, you can use it to narrow your selection of

records. Normally, some output (like tables or graphs) is created that results in more questions about the

resource. Then you can further narrow the selection of records using the previous techniques to produce

more output on the reselected records.

Add to Existing Selection

After you have narrowed a selection (applied New Session or Select from Existing Selection techniques),

you can go back and add more records. Select Session \ Add to Existing Selection. All records (even

those you already have selected) from the most recent selection of RPA subregions are available for addition

to the latest selection of records. The information is made available for addition through the RPA Variable

Selection and Select Field Value(s) dialogs using the steps previously described. Since all the information

from the most recent selection of RPA subregions is provided for addition, some additions may not add any

new records. To prevent duplicate information, RPA Data Wiz will not add records if they already exist in

the latest selection. If necessary, choose Query History to review previous selection criteria.

Exiting RPA Data Wiz

If Exit (under File) is enabled, then it is safe to shutdown RPA Data Wiz. When you are ready, select File \

Exit to quit RPA Data Wiz.

Chapter 4

Working with Tables and Graphs

All of the output tables in RPA Data Wiz are two-way tables made of rows, columns, and cells. You choose the

variables that define the row and column headings and the variable(s) represented in the cells. The tables can

report sums or ratios. As presented below, you can create two variations of the two-way table in RPA Data

Wiz.

RPA Data Wiz produces two-dimensional bar graphs. Stacking bar graphs are produced when working with

sums and nonstacking bar graphs are produced with ratios.

Crosstab Table and Graph Generator

Choose Tables and Graphs \ Crosstab Tables and Graphs to display the Crosstab Table and Graph

Generator.

Creating a Table

In general a crosstab is a table of sums, averages, or some other calculation for a continuous variable grouped

by two or more discrete variables. Each discrete variable can be composed of multiple divisions or classes. For

example, forest type is composed of many classes, such as red pine and sugar maple.

In RPA Data Wiz, the continuous variable is a sum, so it is called the sum variable. Only one sum variable can

be selected. Sums are grouped by up to four variables on the left side of the table (grouping variables defining

row headings) and one variable (pivot variable defining column headings) across the top of the table. This type

of table is commonly created in spreadsheets.

1. Choose one to four grouping variables in the Crosstab Table and Graph Generator. In this case, the

CTRL and SHIFT keys do not add flexibility in selecting multiple variables. Just point and click the

variables you wish to use as grouping variables. If you decide that you do not want a variable already

selected, then click on the variable again. It will be deselected. The order in which you choose the

grouping variables dictates the order in which they appear in the table. The example table below

shows that Owner Group was chosen first, followed by Stand Size Class.

2. Choose one pivot variable to determine the column headings. In this case Forest Type Group was

chosen as the pivot variable.

3. Choose the sum variable to occupy the cells of the table. SW Netgrowth was chosen in this

example.

4. Click Add number of samples as extra column to include the number of RPA plots or records as

an option. This is the sum of the samples associated with each row heading. This is meant to add a
15

measure of accuracy to the estimates displayed in the table. The numbers in the rows with

thousands of associated RPA plots are more reliable than those in the rows with hundreds of

associated plots.

5. Finally, click Create Summary Table to produce a table similar to the example below.

Rarely, the number of column headings exceeds the allowable limit and the table is not created. If this

happens, switch the pivot variable with a grouping variable to achieve the same information in a different

output format. This will work in most situations where there is only one grouping variable of interest.
16

Creating a Graph

In the Crosstab Table and Graph Generator, choose variables of interest as you would when making a table

(see “Creating a Table”) except only choose one grouping variable. Click Create Graph. A two-dimensional

stacking bar graph is created. The classes or divisions of the grouping variable are the series and the classes or

divisions of the pivot variable are the bar categories.

The example below shows the classes of stand-size class as being the bar categories. The series comprise the

divisions of age class. The example shows the 15-year age class as being selected. Select a series with a click of

the mouse in the graph or in the legend, then the corresponding row in the table is also highlighted. This

allows you to see the exact numbers associated with the selected series.

There is another way to clarify and depict the information associated with a single series. You can change the

graph to show only a selected series. While holding the SHIFT key down, click on a series in the graph or

legend. A new graph appears for the selected series. The second example below shows the graph for the 15-

year age class series. The scale bar changes to provide more detail in many cases. Click outside the graph

outline (outside the dotted line) to restore the display to the original graph with all the series. Clicking in the

table does nothing. When a selected series is displayed in a new graph, the series is still highlighted on the

graph and displays with annoying selection brackets. Click within the dotted line but off from the bars or

legend to remove these selection brackets from the display.
17

Multiple Variable Sums Table and Graph Generator

Choose Tables and Graphs \ Multiple Variable Tables and Graphs to display the Multiple Variable

Sums Table and Graph Generator.

Creating a Table

Multiple variable sums table is a name created for tables in RPA Data Wiz that report sums for one or more

continuous variables (sum variables defining column headings) indicated across the top of the table and

grouped by up to four discrete variables (grouping variables defining row headings) on the left side of the

table. The continuous variable(s) can be any number of sum variables listed.

If an optional continuous variable (only for ratios of sums) is chosen, then each sum variable total is

divided by the sum of this optional variable for each unique grouping in the table. The result of this

division, the quotient, will be identified as “undefined” if the sum of the optional variable (the denominator) equals zero. This is useful in a number of ways. Dividing by area results in per acre or per hectare

estimates. Also, you can look at things like the ratio of mortality to netgrowth or the ratio of softwood to

hardwood for the selected plots. Follow these steps.

1. Choose one to four grouping variables in the Multiple Variable Sums Table and Graph Generator. In this case, the CTRL and SHIFT keys do not add flexibility in selecting grouping variables

but do work when selecting sum variables. Point and click the variables you wish to use as

grouping variables. If you decide that you do not want a variable already selected, then click on

the variable again. It will be deselected. The order in which you choose the grouping variables

dictates the order in which they appear in the table. The example table below shows that

StateCounty was chosen first, followed by Administrative Forest.
18

2. Choose one or more sum variables. The example below shows that the variables SW Mortality

through Netgrowth were chosen. The order of column headings in the output table always follows

the order in which sum variables are displayed in this dialog.

3. You may choose an optional ratio variable to divide the sum variable totals. This example shows that

Area was chosen. The result is a table with mortality and netgrowth per acre. Remember that this is

only for the records that were chosen in the session so these numbers may not represent all the plots

in each StateCounty-Administrative forest combination. For example, the user may have only picked

forest stands designated with the large stand-size class.

4. Click Add number of samples as extra column to include the number of RPA plots or records as

an option. This is the sum of the samples associated with each row heading. For tables in this dialog,

this column appears at the end or far right of the table. This is meant to add a measure of accuracy

to the estimates displayed in the table.

5. Finally, click Create Summary Table to produce a table similar to the example below.
19

A second optional ratio can be produced when working with grouping variables associated with maps in

RPA Data Wiz. The Mapping Ratios checkbox is available when one mapping, grouping variable

(StateCounty, Baileys’ Ecosection, 107th or 108th Congressional District Code, Hydrological Accounting

Unit, or Administrative Forest); one sum variable; and one variable in Optional, only for Ratios of Sums are

chosen. If this checkbox is chosen, then a ratio of the sum variable total to the optional variable total in

each geographic unit populates the table. The key is that the optional variable total is the total for all plots

in the geographic unit, even when the records involved with the sum variable totals may only involve a

subset of the plots in the geographic unit. For instance, the user may have only picked forest stands

designated with the large stand-size class but the optional variable total will involve all plots regardless of

stand size. The results would represent the ratio of large stand-size class plots to all stand-size class plots.

Another common output from using this technique would be to produce the ratio of timberland to all land

for each county.

Creating a Graph

In the Multiple Variable Sums Table and Graph Generator, choose variables of interest as you would when

making a table (see “Creating a Table”), except only choose one grouping variable. Click Create Graph. If

no optional ratio variable is chosen then a two-dimensional stacking bar graph is created. The classes or

divisions of the grouping variable are the series, and the sum variables are the bar categories.

The example below shows SW Gross Biomass 6” Class or Larger and HW Gross Biomass 6” Class or Larger

as being the bar categories. The series make up the Forest Type Group. The example shows the Elm-AshCottonwood (East) series as selected. Select a series with a click of the mouse in the graph or in the legend,

then the corresponding row in the table is also highlighted. This allows you to see the exact numbers

associated with the selected series.

As with graphs associated with crosstabs, there is another way to clarify and depict the information

associated with a single series. You can change the graph to show only a selected series. While holding the

SHIFT key down, click on a series in the graph or legend. A new graph appears for the selected series. The

second example below shows the graph for the Elm-Ash-Cottonwood (East) series. The scale bar changes

to provide more detail in many cases. Click outside the graph outline (outside the dotted line) to restore

the display to the original graph with all the series. Clicking in the table does nothing. When a selected

series is displayed in a new graph, the series is still highlighted on the graph and displays with annoying

selection brackets. Click within the dotted line but off from the bars or legend to remove these selection

brackets from the display.
20
21
22

There is a difference in the type of graph displayed if an optional ratio variable is chosen in the Multiple

Variable Sums Table and Graph Generator. Instead of a stacking bar graph, a nonstacking bar graph is created

(see example below). In a stacking bar graph, the top of the bar represents the total sum for the bar category.

This is useful when showing sums; on the other hand, it makes no sense to show ratios as stacking when the

total sum of the ratios for a bar category does not represent the overall ratio. Notice in the example below that

the overall ratio of SW Cubic Foot Volume to HW Cubic Foot Volume is 0.38 (Total row of the associated

table). As explained in the first section of “Creating a Graph,” you can highlight individual series and display

graphs of individual series.
23

Warning Message

If a resulting crosstab or multiple variable table is large, you may see a warning like the one below. What

you do next depends on the speed and memory of your computer. On a 1.8 GHz machine with 1 GB of

memory (a fast computer), the operation below (4,556 records) took 8 minutes.

We recommend trying to create some of the bigger tables and pressing the Stop button on the main menu

if the operation takes too long. After awhile you will gain a sense of how long it takes to create various size

tables on your computer. Keep in mind that given the same number of rows in a table, it takes longer when

more grouping variables are involved.

Problem: Record Headings Filling the Screen?

Sometimes when working with small computer screens and multiple grouping variables (define row

headings), the row headings fill the screen and the rest of the table cells appear to be unavailable. First,

make sure your form sizes are maximized (click on the box in the upper right-hand corner of each form to

maximize the size). If there is still a problem, you will need to narrow the column width for some of the

row headings. Place the cursor on the division line between column headings. Next, click and drag with

the mouse to decrease column width. This should allow you to scroll through the rest of the table.

File Menu and Table Output Options

There are many options for table output from the File menu in RPA Data Wiz. A Save / Print dialog will

appear for each of the formats and you can choose where to save the file. The default is in the temporary

directory, temp, of the RPA Data Wiz application directory.
24

If you have Microsoft Excel installed on your computer, then you can save the table in Excel format. Choose

Save As Excel Table or press CTRL + S to save the table in your version of Excel. This option will not work

if you do not have Excel or if your Excel version is older than Excel 95. The column and row headings are

automatically fixed and appear in bold font when opened in Excel.

The next two output formats are text. Pick Save As Comma Delimited to save the output with table headings

and values separated with commas (“csv” file extension). This format can be imported into many software

applications. Choose Save As Report to save the table in a report format (“txt” file extension).

Finally, select Print Table or press CTRL + P to print the table to a printer using the Print dialog. The

recommendation is to choose landscape for the orientation (the default). Note that you can also save output

tables associated with graphs.

File Menu and Graph Output Options

Like the table output options, there are several options for graph output from the File menu in RPA Data Wiz.

A graph heading does not output with the graph image. This allows you the freedom to make your own title

in a final product using another software package like Microsoft PowerPoint. You can easily import or copy

and paste the graph into another software package.

Choose Save Graph to save the graph in bitmap format. The Save / Print dialog displays and allows you to

save the file in a location of your choice. The default is in the temporary directory, temp, of the RPA Data Wiz

application directory. You can now import the graph into another software package. If you are working in

PowerPoint, select Insert \ Picture \ From File and then choose the file.
25

Choose Copy Graph to Clipboard or press CTRL + G to copy the graph as a Windows metafile to the

Windows clipboard. The data in the graph is also pasted into memory. The clipboard holds copied objects

in memory and not as files. Consequently, you are not asked to save to a file. Depending upon where and

how you perform a paste, the data or the image of the graph is pasted. If you are working in Excel, then

select Edit \ Paste to paste the number data in the spreadsheet. Note that the row heading may not paste

with the rest of the data. This appears to be a Microsoft bug in the software. To paste an image of the graph

into the spreadsheet, choose Edit \ Paste Special... and select the Bitmap type. If you are working in

Microsoft PowerPoint, then the image of the graph will paste into the document. We recommend that you

choose Edit \ Paste Special... and select Device Independent Bitmap; otherwise, the graph may not

paste correctly. You may try pasting in a number of different formats to see what works best for you.

Usually, the bitmap option works well for this situation.

Whether you are opening the image from a saved bitmap or pasting from the clipboard, you may need to

resize the graph to fit your area of interest. This is usually done by selecting the pasted bitmap image and

then changing the size properties of the image or by clicking on a corner of the image and dragging it. In

PowerPoint, select Format \ Picture \ Size and change the size.

Finally, choose Print Table to print the table using the Print dialog. We recommend choosing landscape

for the orientation (the default). Note that you can also save output tables associated with graphs (see “File

Menu and Table Output Options”).
26

Working with Multiple Output Tables in a Spreadsheet

Except when working with ratios, any row containing all zeros will not appear. Likewise, these rows are not

part of the output from RPA Data Wiz. Some large tables result in thousands of rows and many total to 0. By

not displaying or including these rows in output, computer resources are saved and tables are easier to read.

This is important to remember. The disadvantage is that it can cause problems when working with multiple

output tables in one spreadsheet. You may try working with multiple output tables in one Excel sheet and

expect the rows from the tables to match up. Holding everything else constant, output tables with ratios may

have more rows than output tables that report sums. In future versions of RPA Data Wiz, the option to include

rows that total to 0 in any table will probably be added.
27

Chapter 5

Working with Maps

Preparing to View Map

Before creating a map, you must first create a table or graph in the Multiple Variable Sums Table and Graph

Generator (see Chapter 4). Here are the extra requirements for making a map. While creating the table or

graph, select only one mapping, grouping variable and only one sum variable. Any of the other options in

the dialog may also be chosen. The mapping, grouping variables are StateCounty, Baileys’ Ecosection, 107th

or 108th Congressional District Code, Hydrological Accounting Unit, and Administrative Forest.

Make a table using the Multiple Variable Sums Table and Graph Generator and the restrictions mentioned.

Afterwards, select View Map and the appropriate map choice is enabled. The example below shows the

108th Congressional District Code as the grouping variable of choice. Consequently, a 108th Congressional

District map will be developed. Area is the choice for the sum variable and the optional ratio variable. Both

optional boxes are checked. The number of samples associated with each congressional district will be

displayed in the table. Including the number of samples in the table never affects the map. The optional

Mapping Ratios checkbox will result in a different kind of ratio (see “Multiple Variable Sums Table and

Graph Generator” in Chapter 4). During the creation of the initial session (see Chapter 3), timberland only

occurring on public land was chosen for MI, WI, and MN. In this case, checking the Mapping Ratios

checkbox will result in a ratio of public timberland to all land for each congressional district. Consequently, the result will be a 108th Congressional District map of public timberland to all land. The congressional district code is defined in appendix A.
28

View Map

All maps in RPA Data Wiz are classification or choropleth maps, which group the values of the sum variable or

ratios into discrete ranges and represent each range with a different color. Follow the steps below to create

several different types of choropleth maps.

Equal Interval Map

1. Select View Map and the enabled map. The Map form appears. The map view is automatically

zoomed in on the polygons involved. The area of the map displayed is called the map extent.

2. Choose Equal Interval Classes to display a map where the classes have an equal range of values.

3. Change the number of classes by typing in a different number for Number of Classes.

4. Ramp the colors; in other words, change the colors of the classes using a graduated scheme by

selecting the Start Color and End Color.

5. Choose Polygon Labels to display the names of the geographic units.

6. Change the size (points) of the polygon labels by adjusting the number for Label Size. Click

Polygon Labels for the change to take effect.

The example below is the 108th Congressional District map of public timberland acreage to all land acreage

using five equal interval classes. The congressional district labels are also displayed. Notice that the titles on

the maps in RPA Data Wiz are generic, only identifying the variables involved in the output and not including

information indicating any choices made while creating the session.
29
30

Quantile Map

1. Choose Quantile Classes to display a map where the classes are divided such that an equal number

of geographic units occur in each class.

2. Again, change the number of classes by typing in a different number for Number of Classes.

3. As previously mentioned, ramp the colors by selecting the Start Color and End Color.

Again, the example is the 108th Congressional District map of public timberland acreage to all land acreage.

This time, five quantile classes are applied and the congressional district polygon labels are not displayed.

Notice the contrast in the colors and class intervals between this example and the last example.

Custom Map

1. Choose Customize Classes / General Statistics to display a map with user-defined ranges and

colors for each class.

2. Define the class breaks and pick their associated colors. Two breaks are automatically assigned. You

must define at least one more break.

3. There is an option to ramp colors in this dialog. Click the Check to ramp colors from Class 1 to

Last Class box.

The Customize Classes dialog displays some basic statistics such as the mean, minimum, and maximum of the

sum variable or ratio. It also shows the number of geographic units (not counting geographic units labeled as

“Not Applicable” or “Undefined”) involved in the map. These statistics can help determine the distribution of
31

the data and how the classes should be defined. Like the two previous examples, the example below uses

five classes, but the class breaks are defined differently. The same ramping color scheme is applied. Notice

that this user-defined example represents the differences among the congressional districts better than the

two previous examples.
32

Keep in mind that you do not have to select every option before redisplaying a map. Change only the options

you wish. The map will redisplay anytime one of the Equal Interval Classes, Quantile Classes, or Done (in

Customize Classes dialog) buttons is clicked. In addition, the polygon labels are cleared anytime one of these

buttons is clicked.

Applying the GIS Tools

The Map form in RPA Data Wiz provides a number of Geographic Information System (GIS) capabilities. A short

definition for GIS is a system where people apply computer technology to store and manipulate geographic

information. Throughout this chapter, examples have been provided showing how you can manipulate the

geographic information associated with the RPA database. This section describes the GIS tools available in RPA

Data Wiz that are common in most GIS computer applications.

First, notice the Long. Lat. (longitude measuring east-west, latitude measuring north-south) coordinates in

the lower right section of the Map form. Move the cursor throughout the map extent and notice the coordinates changing. The latitude-longitude coordinate system is a common geographic coordinate system used to

identify locations on the earth (Aronoff 1995).

Next, use the cursor to display the exact value associated with a geographic unit. Place the cursor over a

polygon of interest, hold SHIFT, and click the left button on the mouse. The value displays. Notice that the

left-most shaded polygon in the example below is associated with 0.05.
33

The following tools are displayed in the upper-left corner of the Map form. Placing the cursor over each

tool displays a tool tip. Only one of the Zoom In, Zoom Out, or Pan tools can be active at a time. Click one

of the tools and it will function with the cursor while in the map extent.

Zoom In Tool. Activate the Zoom In Tool by clicking it. Hold the left button on the mouse and

drag the cursor over the new map extent. Release the mouse button and the map display will reflect

the new area in a larger map scale (smaller map area displayed in same computer screen area).

Zoom Out Tool. Activate the Zoom Out Tool by clicking it. Unlike the Zoom In Tool, this tool does

not allow you to delineate a box over the area of interest. Click the left button on the mouse over

the point of interest to decrease the map scale by a factor of two.

Pan Tool. Activate the Pan Tool by clicking it. Hold down the left button on the mouse and move

the mouse from one point to another to change the map extent.

Click the next tool and it works immediately to increase the map extent.

Zoom to Full Extent Tool. Activate the Zoom to Full Extent Tool by clicking it. The map extent

changes to show all the geographic units of every map layer present.

Click the tools below to add and delete map layers to and from the map extent. The base map (map that

displays initially in the Map form) cannot be removed. All of the map layers in RPA Data Wiz are located in

the RPA Data Wiz application directory (usually C:\Program Files\RPA Data Wiz\). These map layers are

ArcView shapefiles. You cannot and should not add the same theme that displays as the base map. Doubleclicking on an added map layer name in the legend and then choosing a new color in the Color dialog

changes the color of the map layer. Any polygon shapefiles or polygon, ArcInfo coverages (basically a

different type of map layer) are displayed with no fill color so the base map is not covered. Note that

adding any map layer that does not use the latitude-longitude coordinate system will have unpredictable

consequences. The map layers will not overlay correctly upon each other.

Add Map Layer Tool. Activate the Add Map Layer Tool by clicking it. The Add Map Layers dialog

displays. Choose Shapefile, ArcInfo Polygon or Point Coverage, or ArcInfo Line Coverage. If

Shapefile was chosen, then select Add Layer to use the Open dialog and locate the shapefile of

interest. If an ArcInfo coverage option was chosen, a directory listing appears. ArcInfo coverage

names will appear as directories. Select the one of interest and click Add Layer. Close the Add Map

Layers dialog by clicking the upper-right “X” button on the dialog.
34

Delete Map Layer Tool. Remove an ancillary map layer by first clicking on its name in the legend. Now

click the Delete Map Layer Tool.

Extra map layers can provide a frame of reference. Depending on your audience and the point you are trying

to make, extra map layers like roads and waterways help others relate to the maps you make in RPA Data Wiz.

A number of Web sites offer free digital map layers that work in RPA Data Wiz (e.g., http://data.geocomm.com

and http://nationalatlas.gov/atlasftp.html). Be sure to obtain map layers in the latitude-longitude coordinate

system. A noteworthy extra map layer available with RPA Data Wiz is “statesp020.” This is a State boundary

map layer. The following example shows the congressional districts from previous examples with the previously mentioned state boundary map layer and a road map layer.

A number of Web sites offer free

digital map layers that work in

RPA Data Wiz (e.g., http://

data.geocomm.com and http://

nationalatlas.gov/atlasftp.html).
35

Warnings

Some geographic units have multiple polygons. For example, a county could be composed of an island and

mainland. The island would be coded the same as the mainland area. You can usually tell if a geographic

unit has multiple polygons by selecting Polygon Labels. Multiple polygons that are part of the same

geographic unit will be labeled the same.

In the bottom section of the Map form there is a warning indicating that polygons larger than the selected

working area are pseudo coded based upon the smaller working area information. What does this mean?

The previous examples showed congressional districts that follow State boundaries. It was mentioned

earlier that the session leading up to the examples narrowed the working RPA plots or records down to

public timberland in MI, MN, and WI. In this situation, the warning does not apply because the congressional districts do not move outside of the State boundaries chosen as the selected working area. Suppose

the example is changed by one factor. Instead of creating a 108th Congressional District Map, a Baileys’

Ecosection Map is created. Look at the example below and note where the State boundaries (statesp020)

are in comparison to the ecosection boundaries (ecoregs). Now the warning applies. Some of the

ecosection geographic units extend outside of the tri-state boundary area (the smaller working area). These

ecosections are coded based only upon information occurring in the tri-state area. In other words, even

though the map shows ecosections extending past State boundaries, the color codes of the ecosections only

reflect plot information for the selected States.
36

The 107th and 108th Congressional District Codes, Baileys’ Ecosections, and Hydrological Accounting Units

were assigned to plots using a GIS overlay analysis (appendix A). The analysis was applied using fuzzed plot

locations. The fuzzed locations are usually within a mile of the true plot location. Consequently, there is some

error introduced in the estimates when grouping by these variables. Furthermore, the maps associated with

these variables will inherit this error. The StateCounty and Administrative Forest codes were directly assigned

using the correct plot locations, so the estimates and maps associated with these grouping variables are not

subject to this error.

File Menu and Map Output Options

As with tables and graphs, a number of output options are available for maps in RPA Data Wiz. The legend

and the map are output separately to allow more freedom when producing a final product in another software

package like Microsoft PowerPoint or Adobe Photoshop. You can import or paste the legend and map into

another software package and manipulate them to suit your needs. A map title does not come with the map

image. This allows you the freedom to make your own title. The map can be output as a bitmap or a Windows

enhanced metafile. Windows metafiles sometimes result in a sharper image, especially when the map has

many line features like roads or waterways. However, the bitmap usually handles manipulation better than the

metafile. Sometimes resizing the metafile adversely alters the image. Bitmap is the safest format to use.

Exporting the Map and Legend

1. Choose File \ Export Map to display the Save – Copy dialog.

2. Select Export to Bitmap or Export to Windows Enhanced Metafile.

3. Click Export to save the map portion of the Map form.

4. Close the Save - Copy dialog by clicking the upper-right “X” button on the dialog. If you are

working in PowerPoint, select Insert \ Picture \ From File and then choose the file.

5. Choose File \ Export Legend to save the legend as a bitmap. The output files can be saved to any

available directory, but the default directory is “temp” in the RPA Data Wiz application folder.
37

Copying the Map and Legend to the Windows Clipboard

1. Select File \ Copy Map to Clipboard to display the Save – Copy dialog. The clipboard holds

copied objects in memory and not as files. Consequently, you are not asked to save to a file.

2. Select Copy as Bitmap or Copy as Windows Enhanced Metafile.

3. Click Copy Map to Clipboard to copy the map portion of the Map form to the Windows

clipboard.

4. Close the Save - Copy dialog by clicking the upper-right “X” button on the dialog. Now you can

paste the map into another software program. If you are working in PowerPoint and you chose

bitmap, we recommend you choose Edit \ Paste Special... and select Device Independent

Bitmap. If you are working in PowerPoint and you chose Windows enhanced metafile, we

recommend you choose Edit \ Paste Special... and select Picture (Enhanced Metafile).

5. Choose File \ Copy Legend to Clipboard to automatically copy the legend to the clipboard. The

legend only copies in the bitmap format. The legend is now ready to be pasted into another

software program. In PowerPoint, choose Edit \ Paste Special... and select Device Independent

Bitmap.

Whether you are opening the image from a saved file or you are pasting from the clipboard, you may need

to resize the map to fit your area of interest. This is usually done by selecting the pasted image and then

changing the size properties of the image or by clicking on a corner of the image and dragging it. In

PowerPoint, select Format \ Picture \ Size and change the size making sure not to change the east-west

and north-south dimensions disproportionately.

Select File \ Print Map to display the Print dialog and print the map portion of the Map form. The legend

and title will not be printed. Landscape is the recommended and default orientation.
Figure 1 is an example of a final product produced in less than 15 minutes in PowerPoint. Notice that this is

the example map presented in “View Map.” The map layer, statesp020, that comes with RPA Data Wiz was

added in the Map form and the class intervals were customized (used Customize Classes dialog) to bring out

the contrast among the congressional districts. The map and legend were each copied to the clipboard and

pasted into PowerPoint as bitmaps. A north arrow was added from the clip art in PowerPoint. Text was added

to label the states. Finally, a new title was created and the legend was labeled as “Legend.”

Quantile and Equal Interval Mapping – Discussion and Notes

Theoretically, quantile classes have an equal number of geographic units. The total number of geographic units

is divided by the total number of classes to come up with the number of units in each class. If you have 16

units and you want to group them into 4 quantile classes, then there should be 4 units in each class. The first

class should have the first 25 percent of the units. The second class should have the next 25 percent of the

units and so forth. The values of the variable in question (e.g., acreage) are sorted and each geographic unit is

placed in a class based upon the relative magnitude of its value (fig. 2 and table 1). Practically, there are some

complications with the definition given and RPA Data Wiz compensates for these complications.

Theoretically, equal interval classes have an equal range of values. The range of data values (max - min) is

divided by the total number of classes to determine the range of values in each class (fig. 2 and table 1).

Again, there are some complications with this definition and RPA Data Wiz compensates for these.

Quantile Class Exceptions

In RPA Data Wiz, there are some exceptions to the definition of quantile classes. First, if the resulting

quotient is not an integer, then the quotient is truncated. Consequently, there may not be an equal number

of geographic units per class. For example, if there are only 10 geographic units and 6 classes are requested, the result is 1 (10/6 = 1.66, truncated to 1) geographic unit per class (fig. 2 and table 2). With 6

classes and 1 geographic unit per class, only 6 of the 10 geographic units are recognized. In this situation,

RPA Data Wiz puts 5 geographic units in the last class with the greatest upper limit. The last class will have

a disproportionately greater number of geographic units. RPA Data Wiz does not round quotients up; the

result would be a deficient number of classes (2 geographic units in the previous example results in only 5

classes). As the ratio of geographic units to classes increases, this exception has less of an effect. Most of the

time, you will be working with enough geographic units to make the effects of this exception minimal.

39
Table 2.—Quantile mapping using 6 classes and a truncated range of 1 with data from figure 2

Class 4 D 22 - 22 < 23

Class 5 E 24 - 24 E < 25

Class 6 F 30 - 30 FGHIJ < 74

The second exception occurs when more than 1 class has the same upper limit. Notice in table 1 that Class 1

and Class 2 each have 22 as the upper limit in the “Theoretical Ranges” column. The problem becomes worse

when using more classes. Notice in table 2 that now there are 3 classes with 22 as the theoretical upper limit.

Geographic units with the same value can belong to different classes using the quantile mapping technique.

However, RPA Data Wiz keeps all the geographic units with the same values in the same class and displays

them with the same color even though the legend indicates there are multiple classes for the same value.

Figure 3 shows a quantile classification where 4 different classes have the same upper limit of 0.01, but all

counties in the map with 0.01 are shaded with the same color (the topmost color for 0.01 in the legend).

Figure 3.—Quantile map of SW to HW cubic-foot volume on timberland in MN.

40
Equal Interval Class Exceptions

The equal interval mapping technique in RPA Data Wiz can result in exceptions to the definition (fig. 2 and

table 1). As previously mentioned, the range is divided by the number of requested classes. If the quotient

is not an integer, then the quotient is rounded to the nearest integer. In table 1 and figure 2, the range is 61

(73 – 12) and the quotient is 12.2 (61/5). Consequently, the quotient is rounded to provide a class interval

of 12. When rounding down, some geographic units with high values may not be recognized in the last

class. In table 1, County J does not make it into the “Theoretical Counties” column. When rounding up,

the uppermost limit of the greatest class can result in a value greater than the maximum value of the

geographic units. RPA Data Wiz violates the equal interval class definition and always uses the maximum

value to define the uppermost limit of the greatest class. Consequently, the interval for the greatest class

may not equal the interval used for all the other classes. This ensures that all geographic units are accounted for and the uppermost limit in the legend provides extra information (working with all values

except ratios the uppermost limit is 1 more than the maximum value; the uppermost limit working with

ratios is 0.01 more than the maximum value).

Creating the Most Informative Map

When creating your map, you should usually focus on the following rules:

• Maximize the between-class differences

• Minimize the within-class differences

Quantile or equal interval maps can sometimes meet the previous criteria. However, problems do arise

with these techniques. The quantile mapping technique can place geographic units with the same value in

different classes and it can group geographic units with drastically different values in the same class (table

1). The equal interval mapping technique can create classes that contain no geographic units (Class 3 in

table 1, Classes 3 and 4 in table 2). The Customize Classes dialog allows you to overcome these problems

by entering your own class breaks derived by any means you choose. The easiest way to observe the

previous rules is to study the data in the table and find the naturally occurring breaks. You may wish to

export the data to a spreadsheet and then sort it to find the natural breaks. After identifying these breaks,

you can enter them in the Customize Classes dialog.

There may be times when you are not concerned with maximizing the differences among groups that

appear naturally in a map. For example, you may be only interested in highlighting geographic units that

are above or below some threshold value. In this case, you may elect to group everything into two classes

even though there may be a number of naturally occurring groups in each of these classes. Ultimately, your

objectives will dictate the number and location of class breaks for your map.

9. Choose Create Summary Table (see example below). Note that this is not the final table with

the ratios of national forest timberland to private timberland by 108th Congressional District. RPA

Data Wiz cannot directly provide this information. With a few steps, you can derive the information by using this table in a spreadsheet like Microsoft Excel.

55
10. Work with the table in a spreadsheet to derive the ratio. If you have Excel, output the table in Excel

format.

A. Choose File \ Save As Excel Table. Save the file.

B. Start Excel and choose File \ Open. Choose the file you just saved in RPA Data Wiz.

C. Create a new column with the ratio of national forest timberland to private timberland.

1. In a non-occupied column, select a cell in the second row (the first row under the column

headings).

2. In the cell, type the formula that will divide the column of national forest ownership by the

column of private ownership (e.g., “= B2/D2”).

3. Press ENTER.

4. Now select the cell again. Copy the cell (select Edit \ Copy).

5. Select the rest of the cells in the current column that are associated with a congressional

district (including the total) and paste the formula in these cells (select Edit \ Paste). The

resulting numbers are the ratios of national forest timberland to private timberland by

108th Congressional District (see example below). You can express these numbers as

percentages by adjusting the formula (e.g., “= (B2/D2) * 100”).

Exercise 4: Wildlife Habitat Identification

In this exercise you will identify counties that have critical habitat for animals. Birds and mammals use

dead trees like snags for shelter. The pileated and red-headed woodpeckers favor larger snags (> 20-inch or

> 50-cm size classes). Medium snags (10- to 20-inch or 25- to 50-cm size classes) are used by squirrels and

the American kestrel. Birds like the eastern bluebird and black-capped chickadee prefer smaller snags (6-

to 10-inch or 15- to 25-cm size classes). In addition, many animals opt to live in particular forest types at

specific ages. For example, gray squirrels prefer hardwood stands like oak that are mature enough to

provide shelter and food. This exercise will help identify some counties that may have higher preference

for some species based upon the dead wood present. You will use Salvable Dead Biomass 6” Class or Larger

(salvable dead biomass 15-cm class or larger in metric version) to indicate the amount of shelter available.

Tables and Graphs - Salvable Dead Biomass 6” Class or Larger

1. If RPA Data Wiz is not already running, then start it. Typical way is to select Start \ Programs \

RPA Data Wiz.

2. Click in the gray area of the initial screen to start.

3. If you have the English and metric versions, then pick one of them.

4. Choose Session \ New Session.

5. Select North Central Assessment Subregion in Select RPA Subregion(s).

6. Click Done Selecting RPA Subregion(s).

7. Select State in RPA Variable Selection.

8. Choose WI in Select Field Value(s).

9. Click Done Selecting Field Value(s).

10. Choose Land Cover Class in RPA Variable Selection.

11. Select Forest Land in Select Field Value(s).

12. Click Done Selecting Field Value(s).

13. Choose Done Selecting in RPA Variable Selection.

14. Create a table with biomass per area estimates for each county.

A. Choose Tables and Graphs \ Multiple Variable Tables and Graphs. The Multiple Variable

Sums Table and Graph Generator dialog appears.

B. Select StateCounty for the grouping variable.

C. Select SW Salvable Dead Biomass 6” Class or Larger, HW Salvable Dead Biomass 6”

Class or Larger, and Salvable Dead Biomass 6” Class or Larger for the sum variables (15

cm class or larger for metric version). Use CTRL or SHIFT when selecting.

D. Select Area as the optional ratio variable (under “Optional, only for Ratio of Sums:”).

E. Choose Create Summary Table. Notice that Iron, Menominee, and Rock Counties have the

highest salvable dead biomass per area and that most of this is hardwood (HW).

15. Create a new session focusing on Iron, Menominee, and Rock Counties.

A. Choose Session \ Select from Existing Selection.

B. Choose StateCounty in RPA Variable Selection.

C. Select WI, Iron; WI, Menominee; and WI, Rock from Select Field Value(s) using CTRL +

Click.

D. Click Done Selecting Field Value(s).

E. Select Done Selecting in RPA Variable Selection.

16. Choose Query History to see the queries you have performed so far.

17. Close the Query History form.

18. Create histograms comparing the amount of SW and HW salvable dead biomass in 6 inch or

larger classes among the three counties.

A. Choose Tables and Graphs \ Multiple Variable Tables and Graphs.

B. Select StateCounty for the grouping variable.

57
C. Select SW Salvable Dead Biomass 6” Class or Larger, HW Salvable Dead Biomass 6” Class

or Larger, and Salvable Dead Biomass 6” Class or Larger (15 cm class or larger for metric

version) for the sum variables.

D. Select Area for the optional ratio variable.

E. Choose Create Graph (see example below). Make sure your form sizes are maximized to see

the graph well (click on box in upper right-hand corner of each form to maximize size). Look

especially at the salvable dead biomass section of the graph (SW and HW combined). There is

not much difference among the counties on a per area basis.

F. Choose Tables and Graphs \ Multiple Variable Tables and Graphs again. Make the same

histogram except do not choose an optional ratio variable. This shows the total dead biomass

sums for each county. This is a cumulative histogram unlike the previous histogram. The graph

and table show a great difference in totals among the counties with Iron County having more

than the other two counties combined. Note that Iron County is much larger. Iron County

definitely has the most salvable dead biomass in the 6-inch or larger class

58
19. Look at the salvable dead biomass in the available forest types and age classes by stand diameter

class for each of the three counties.

A. Choose Tables and Graphs \ Crosstab Tables and Graphs.

B. Select StateCounty, Forest Type Group, and Ageclass for the grouping variables.

C. Select Mean Stand DIA 2” Class or Larger (5-cm class or larger for metric version) for the

pivot variable.

D. Select Salvable Dead Biomass 6” Class or Larger (15-cm class or larger for metric version)

for the sum variable.

E. Click Create Summary Table. Look at the Total row on the bottom. Notice that most of the

salvable dead biomass is present in the smaller stand-size classes (8-inch or 20-cm mean

stand-size class and smaller). There is no salvable dead biomass listed for forest stands larger

than the 14-inch mean stand-size class (35-cm mean stand-size class). Look at the Total

column on the right. You can quickly scan the relative amounts of salvable dead biomass for

each county-forest type-age class combination. Depending upon the animal species in

question, one county can hold more promise than the others.

20. Compare the amount of salvable dead biomass among forest types.

A. Choose Tables and Graphs \ Crosstab Tables and Graphs.

B. Select Forest Type Group as the grouping variable.

C. Select Mean Stand DIA 2” Class or Larger (5-cm class or larger for metric version) for the

pivot variable.

D. Select Salvable Dead Biomass 6” Class or Larger (15-cm class or larger for metric version)

for the sum variable.

E. Click Create Graph (see example next page). The histogram shows Maple-Beech-Birch with

the most salvable dead biomass.

59
F. Use SHIFT + click to select the Maple-Beech-Birch series on the graph. A new histogram

showing only the Maple-Beech-Birch series appears and the Maple-Beech-Birch series is

highlighted in the table. This forest type comprises approximately half of the total salvable

biomass for the three counties.

G. Click outside the present histogram to return to the original graph. The graph clearly shows

that most of the salvable dead biomass is in the 6-inch mean stand-size class (15-cm mean

stand-size class).

21. Assuming salvable dead biomass in the 6-inch or larger classes signifies dead snags, this analysis

highlights several counties in Wisconsin that may have favorable habitat for animal species preferring smaller forest stand sizes in the Maple-Beech-Birch forest type.

Map - Salvable Dead Biomass 6” Class or Larger

1. Create a table of salvable dead biomass per area for each county.

A. Choose Tables and Graphs \ Multiple Variable Tables and Graphs

B. Select StateCounty for the grouping variable.

C. Select Salvable Dead Biomass 6” Class or Larger (15-cm class or larger for metric version) for

the sum variable.

D. Select Area for the optional ratio variable.

E. Select Create Summary Table.

2. Identify the natural groupings or groupings of interest for the biomass per area estimates associated

with the counties. Output the table to read into a spreadsheet and sort the biomass per area estimates. If you have Microsoft Excel, output the table in Excel format.

A. Choose File \ Save As Excel Table and save the file.

B. Open the file in Excel.

C. Delete the first (row headings) and last (totals) rows. Select the last row and choose Edit \

Delete. Select the first row and choose Edit \ Delete.

D. Select both columns of numbers and choose Data \ Sort. Sort by column B, the salvable dead

biomass per area column. Look at the sorted biomass numbers. Look for natural or interesting

groupings and breaks in the sorted numbers. Identify 5 or more breaks that you think delineate

the groups. Remember these break numbers for later. 60
3. Select View Map \ County Map. A county map appears.

4. Select Equal Interval Classes with the default of 5 classes.

5. Select Quantile Classes with the default of 5 classes. Notice the difference. The map and legend

indicate that most counties have relatively low amounts of salvable dead biomass per area in the

6-inch and larger classes.

6. Choose Customize Classes / General Statistics. Look at the Statistics Info section.

A. Type in numbers for the class breaks you previously identified.

B. Check Check to ramp colors from Class 1 to Last Class.

C. Click on the Last Class color box and change the color to Maroon.

D. Select Done but leave the Customize Classes dialog open. Move the dialog so you can see the

map.

E. Compare your custom map to the equal interval and quantile class maps by selecting the

Equal Interval Classes and Quantile Classes buttons. Experiment with the number of

classes designated with each type of map. Which is the best map? The answer to this can

vary depending upon your objective. You may want a map that does the best job of identifying the differences in salvable dead biomass per area among all the counties. In this case, you

will need a number of classes (e.g., 5 or more) preferably occurring close to any natural

breaks. In contrast, you may only wish to highlight the few counties with the highest

salvable dead biomass per area. With this objective in mind, a few classes would suffice.

Below is an example where the class intervals were set manually using the Customize Classes

dialog.

7. Close the Map and Output Table forms.

8. Choose File \ Exit to stop the program.

Appendix A

Selection Variables

These are the definitions for the selection variables in RPA Data Wiz. The corresponding field names in the

RPA Data Wiz databases (English, rpadb2002.mdb; metric, rpadb2002met.mdb) are also provided. RPA

Data Wiz uses Microsoft Access databases. Most of the data in RPA Data Wiz (rpadb2002.mdb and

rpadb2002met.mdb, Access databases) originally came from the 2002 RPA Assessment database, an Oracle

database. Most of the definitions presented here come directly from The 2002 RPA Plot Summary Database

Users Manual Version 1.0 (Miles and Vissage, In prep.) associated with the 2002 RPA Assessment database.

Some fields have been added and some field definitions have been modified to work in RPA Data Wiz. The

field definitions that may be unique to RPA Data Wiz or may have been changed to work in RPA Data Wiz

are marked with an asterisk. The definitions follow the order presented in the RPA Variable Selection dialog

of RPA Data Wiz. D.b.h. (diameter at breast height) is mentioned in this appendix. It is defined as the stem

diameter, outside bark, at a point 4.5 feet (137.16 cm) above ground. Any other variables mentioned but

not defined in this appendix are defined by Miles and Vissage (In prep.).

6. *StateCounty A combined State-county FIPS code ((STATE * 1000) + COUNTY). This field provides a unique identifier for

STATE and COUNTY each county in the country. FIPS codes for States are unique, but FIPS codes for counties are not unique

among States. Consequently, StateCounty was created. Some special codes represent areas other than

counties.

10. *Administrative A combined administrative unit-administrative forest code. The field name for the USDA Forest Service

Forest administrative unit code in the RPA database is ADMINFORU. In the RPA database, the field name for the

ADMINFORU and administrative forest within a specific unit is ADMINFOR. The RPA Data Wiz field, ADMINFORU, is a

ADMINFOR from combination of the two previous RPA database fields ((ADMINFORU * 100) + ADMINFOR). This code

RPA database identifies the polygons in the usfs shapefile used in RPA Data Wiz to map lands administered by the USDA

modified to Forest Service. The usfs shapefile is a combination of the Automated Lands Project, Federal Lands and Indian

ADMINFORU in Reservations of the United States (National Atlas Program), and the USFS Region 5 Administrative Boundaries

RPA Data Wiz maps. See the metadata associated with the usfs shapefile metadata (usfs.met or usfs.shp.xml located in the

percent of the stocking in medium- and large-diameter trees and with the stocking of largediameter trees equal to or greater than the stocking of medium-diameter trees

21. *Ageclass Stand age. In RPA Data Wiz, the average total age, to the nearest 5 years, of the trees (plurality of all live

AGECLASS trees not overtopped) in the predominant stand-size class of the condition, determined using local procedures. Age is difficult to measure and therefore stand age may have large measurement errors. Nonstocked

stands are recorded as 0. Any inventory dated 1995 or later contains stand ages recorded to the nearest year,

but these were recoded to the nearest 5 years (required for RPA Data Wiz). For some older inventories, stand

age was recorded using intervals of 10 or 20 years (CT, DE, KY, MD, NH, PA, RI, VT, and WV) for stands

< 100 years old, 20-year age classes for stands between 100 and 200 years, and 100-year age classes if older

than 200 years. The value recorded is the midpoint of the age class. Mixed age classes were allowed in older

inventories (AR, CT, KY, LA, ME, MA, MS, NH, NY, OH, OK, PA, RI, TX, VT, and WV) and were assigned a

coded value of -999.

22. Percent Stocking Percent stocking class. A coded value indicating the percent stocking class for growing stock in the stand.

Class The 10 percent interval classes range from nonstocked to 100 percent stocking, relative stocking basis. All 10

STOCKPC of these codes were used for Hawaii and interior Alaska. Only codes 1, 3, 5, 7, 9, and –1 were used for the

other 48 States (the STOCKPC data for these States came from the GSSTKCD variable in the FIADB, which

has fewer classes than STOCKPC). For the other 48 States, a code of 1 is equivalent to Nonstocked, 3 equals

1 Regeneration without site preparation: The area is characterized by the absence of a manageable

stand because of inadequate stocking of growing stock. Growth will be much below the potential

for the site if the area is left alone. Prospects are not good for natural regeneration. Artificial

regeneration will require little or no site preparation.

2 Regeneration with site preparation: The area is characterized by the absence of a manageable stand

because of inadequate stocking of growing stock. Growth will be much below the potential for the

site if the area is left alone. Either natural or artificial regeneration will require site preparation.

3 Stand conversion: The area is characterized by stands of undesirable, chronically diseased, or offsite (found where not normally expected) species. Growth and quality will be much below the

potential for the site if the area is left alone. The best prospect is for conversion to a different forest

type or species.

4 Thinning seedlings and saplings: The stand is characterized by a dense stocking of growing stock.

Stagnation appears likely if left alone. Stocking must be reduced to help crop trees attain dominance.

5 Thinning poletimber: The stand is characterized by a dense stocking of growing stock. Stocking

must be reduced to prevent stagnation or to confine growth to selected, high-quality crop trees.

6 Other stocking control: The stand is characterized by an adequate stocking of seedlings, saplings,

and poletimber growing stock, mixed with competing vegetation either overtopping or otherwise

inhibiting the development of crop trees. The undesirable material must be removed to release

overtopped trees, to prevent stagnation, or to improve composition, form, or growth of the residual

stand.

7 Other intermediate treatments: The stand would benefit from other special treatments, such as

fertilization, to improve the growth potential of the site, and pruning to improve the quality of

individual crop trees.

8 Clearcut harvest: The area is characterized by a mature or over-mature sawtimber stand of sufficient volume to justify a commercial harvest. The best prospect is to harvest the stand and

regenerate.

9 Partial cut harvest: The stand is characterized by poletimber- or sawtimber-size trees with sufficient

merchantable volume for a commercial harvest that will meet intermediate stand treatment needs

or prepare the stand for natural regeneration. The stand has a favored species composition and

may be even- or uneven-aged. Included are such treatments as commercial thinning, seed tree, or

shelterwood regeneration and use of the selection system to maintain an uneven-age stand.

10 Salvage harvest: The stand is characterized by excessive damage to merchantable timber because of

fire, insects, disease, wind, ice, or other destructive agents. The best prospect is to remove damaged or threatened material.

11 No treatment: No silvicultural treatment is needed.

ECOSECTION into one numeric code. The corresponding alphanumeric code exists in the field EcosectionTxt, only present

in the database used with RPA Data Wiz. The translation from Baileys’ alphanumeric ecocode to this integer

value was taken from GTR SRS-36 (Rudis 1999) located in the references directory of the RPA Data Wiz CD.

Plots were assigned an ecocode using an overlay analysis where plots with fuzzed (usually within a mile of the

true location) locations were overlaid onto a Baileys’ ecoregion polygon layer. Each plot was assigned the code

of the ecoregion it contacted. If a plot did not intersect with a polygon, then it was assigned the ecoregion

code of the polygon with the closest centroid. More information is available with the metadata (ecoregs.met

or ecoregs.shp.xml in the application directory) of the ecoregs shapefile associated with RPA Data Wiz.

District Code and a State from which a member of the U.S. House of Representatives is elected. There are 435 congressional

108th Congressional districts in the United States apportioned to the States based on population. Each State receives at least one

District Code congressional district. The congressional district codes for the 107th and 108th Congress were assigned to each

CONGCD and plot (regardless of when it was measured). CONGCD and CONGCD108 are four-digit numbers. The first two

CONGCD108 digits are the State FIPS code and the last two digits are the congressional district number. Plots were assigned

congressional districts using an overlay analysis where plots with fuzzed (usually within a mile of the true

location) locations were overlaid onto a congressional district polygon layer. Two overlay analyses were

performed, one for the 107th and one for the 108th. Each plot was assigned the code of the congressional

district it contacted. If a plot did not intersect with a polygon, then it was assigned the congressional district

of the polygon with the closest centroid. If a plot was assigned a CONGCD or CONGCD108 that represented

a congressional district from the incorrect State, then a visual inspection was used to assign the congressional

district code of the closest polygon in the correct State (indicated by the State FIPS code associated with the

plot). This situation occurred with plots near State borders due to the fact that the plot locations are fuzzed.

More information is available with the metadata of the cgd107 and cgd108 shapefiles associated with RPA

Output Variables (English Version)

These are the definitions for the output variables in the English version of RPA Data Wiz. The corresponding field names in the RPA Data Wiz database, rpadb2002.mdb, are also provided. Most of the data in RPA

Data Wiz (db2002.mdb, Access database) originally came from another database, the 2002 RPA Assessment database. Most of the definitions presented here are modified versions of those in The 2002 RPA Plot

Summary Database Users Manual Version 1.0 (Miles and Vissage, In prep.) associated with the 2002 RPA

Assessment database. Field definitions have been modified to work in RPA Data Wiz. In the original 2002

RPA Assessment database, these output variables were expressed on a per acre basis. To speed up computations in RPA Data Wiz, these output variables, except area, were multiplied by their corresponding

expansion factors (VEF) to come up with totals for each plot or record in the RPA Data Wiz database. The

volume expansion factor, or VEF, is the number of acres the sample plot represents for making total

estimates of volume, number of trees, and biomass. Sometimes other variables are mentioned in this

appendix. Please refer to appendix A for definitions of selection variables like TSOURCE. Refer to appendix D for definitions of size classes. D.b.h. or diameter at breast height is mentioned in this appendix. It is

defined as the stem diameter, outside bark, at a point 4.5 feet (137.16 cm) above ground. Any other

variables mentioned but not defined in this appendix are defined by Miles and Vissage (In prep.).

Output Variables (Metric Version)

These are the definitions for the output variables in the metric version of RPA Data Wiz. The corresponding

field names in the RPA Data Wiz database, rpadb2002met.mdb, are also provided. Most of the data in RPA

Data Wiz (rpadb2002met.mdb, Access database) originally came from another database, the 2002 RPA

Assessment database. Most of the definitions presented here are modified versions of those in The 2002 RPA

Plot Summary Database Users Manual Version 1.0 (Miles and Vissage, In prep.) associated with the 2002 RPA

Assessment database. Field definitions have been modified to work in RPA Data Wiz. In the original 2002 RPA

Assessment database, these output variables were expressed on a per acre (not hectare) basis. To speed up

computations in RPA Data Wiz, these output variables, except area, were multiplied by their corresponding

expansion factors (VEF) to come up with totals for each plot or record in the RPA Data Wiz database. The

volume expansion factor, or VEF, is the number of acres the sample plot represents for making total estimates

of volume, number of trees, and biomass. After calculating the output variable totals per plot, a metric

conversion factor was applied to the English units. Acres were converted to hectares (acres * 0.404686).

Cubic-foot values were converted to cubic meters (cubic feet * 0.028317). Pounds were converted to metric

tons (pounds * 0.000453592). Sometimes other variables are mentioned in this appendix. Please refer to

appendix A for definitions of selection variables like TSOURCE. Refer to appendix D for definitions of size

classes. Centimeters mentioned in the definitions below are rounded to the nearest integer. Inches were

converted to centimeters using 2.54 as the conversion factor. D.b.h. or diameter at breast height is mentioned

in this appendix. It is defined as the stem diameter, outside bark, at a point 4.5 feet (137.16 cm) above

ground. Any other variables mentioned but not defined in this appendix are defined by Miles and Vissage (In

prep.).

 RPA Data Wiz is a computer application used to create summary tables, graphs, and maps of Resource Planning Act (RPA)

Assessment forest information (English or metric units). Volumes

for growing stock, live cull, dead salvable, netgrowth, and mortality

can be estimated. Acreage, biomass, and tree count estimates are

also available.

KEY WORDS: RPA, assessment, forest, inventory, GIS, maps,

metric, database.
