Since its founding, NASA has been dedicated to

the advancement of aeronautics and space

science. The NASA Scientific and Technical

Information (STI) Program Office plays a key

part in helping NASA maintain this important

role.

The NASA STI Program Office is operated by

Langley Research Center, the lead center for

NASA's scientific and technical information. The

NASA STI Program Office provides access to

the NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA's institutional

mechanism for disseminating the results of its

research and development activities. These

results are published by NASA in the NASA STI

Report Series, which includes the following

report types:

• TECHNICAL PUBLICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data or

theoretical analysis. Includes compilations of

significant scientific and technical data and

information deemed to be of continuing

reference value. NASA's counterpart of

peer-reviewed formal professional papers but

has less stringent limitations on manuscript

length and extent of graphic presentations.

BOREAS Forest Cover Data Layers over the SSA-MSA in Raster Format

Jaime Nickeson, Fern Gruszka

Summary

This data set, originally provided as vector polygons with attributes, has been processed by BORIS

staff to provide raster files that can be used for modeling or for comparison purposes. The original data

were received as ARC/INFO coverages or as export files from SERM. The data include information on

forest parameters for the BOREAS SSA-MSA. Most of the data used for this product were acquired by

BORIS in 1993; the maps were produced from aerial photography taken as recently as 1988. The data

are stored in binary, image format files.

Note that the binary files of this data set on the BOREAS CD-ROMs have been compressed using

the Gzip program. See Section 8.2 for details.

3. Theory of Measurements

SERM-FBIU maintains in its inventory unit a GIS of forest inventory information for Saskatchewan.

This inventory is maintained primarily for use by forest managers for silvicultural purposes, and it

contains a wealth of information that can be of use in Earth resources analyses and ecosystem

modeling either in its raw form or as a derived product such as this one.

4. Equipment

4.1 Sensor/Instrument Description

The original polygon data were digitized from 1:12,500-scale forest cover maps. The maps were

derived from black-and-white 1:12,500-scale infrared aerial photography and field reconnaissance

notes. No information is known about the original digitizing equipment or procedures and criteria used

in the digitizing process.

4.1.1 Collection Environment

These original vector data were acquired as ARC/INFO vector coverages or in ARC/INFO export

7.1.4 Projection

The area mapped is projected in the BOREAS grid projection, which is based on the ellipsoidal

version of the Albers Equal-Area Conic (AEAC) projection. The projection has the following

parameters:

Datum: North American Datum of 1983 (NAD83)

Ellipsoid: Geodetic Reference System GRSe0 or WGS84

Origin: iii.000 ° West Longitude

51.000 ° North Latitude

Standard Parallels: 52 ° 30' 00" N

58 ° 30' 00" N

Units of Measure: kilometers

7.1.5 Grid Description

The data are gridded in 30-m intervals based on the ellipsoidal version of the AEAC projection with

standard parallels of 52 ° 30' N and 58 ° 30' N and a lower left origin of 51 ° N and 111 ° W.

7.2 Temporal Characteristics

Most of the data used for this product were acquired by BORIS in 1993. The maps from which the

data are derived are completely reinventoried on a 10- to 20-year cycle by SERM, except for disturbed

areas, which are updated annually. BORIS acquired the data in 1993; the forest cover layers have not

yet had any inventory updates.

7.2.1 Temporal Coverage

These maps were produced from aerial photography taken as recently as 1988. The data base

maintained by SERM is updated as needed based on fires, cutting, or other disturbances.

7.2.2 Temporal Coverage Map

Not available.

7.2.3 Temporal Resolution

As noted, the original maps are completely reinventoried by SERM personnel on a 10- to 20-year

cycle, except for disturbed areas, which are updated annually. The photographs and other information

used to create the original vector data set most likely covered the 10- to 20-year period prior to 1988

and any updates made from then to 1993, when the data were acquired.

8. Data Organization

8.1 Data Granularity

The smallest amount of obtainable data is the entire data set containing the four raster layers and

other supporting files.

8.2 Data Format(s)

The raster data are stored on tape as single-byte band-sequential binary files.

8.2.1 Uneompressed Data Files

The data files include:

Record Number of

File Description Size (Bytes) Records Bytes/Pixel

i Header File 80 19 N/A

2 SPECIES COVER 1443 1145 i

3 CROWN CLOSURE 1443 1145 1

4 HEIGHT 1443 1145 1

5 YEAR 1443 1145 1

6 AML 1 (calc cover, year) 80 79 N/A

7 AML 2 (create grid, combine) 80 129 N/A

8 AML 3 (reprojection info) 80 i0 N/A

The data set consists of eight files. The first file is the header file, which contains 80-byte records of

American Standard Code for Information Interchange (ASCII) characters that describe the general

content of the data set.

Files 2 through 5 contain the binary raster data layers. Each raster layer contains 1,443 8-bit

(1-byte) values in each of 1,145 lines.

Files 6 through 8 contain ASCII files that provide examples of the type of ARC Macro Language

(AML) files used to create this data set from the original vector data. These files were not intended to

be used directly; they are merely examples of the process undertaken to produce the provided data set.

8.2.2 Compressed CD-ROM Files

On the BOREAS CD-ROMs, files 1, 6, 7, and 8 listed above are stored as ASCII text files;

however, files 2 - 4 have been compressed with the Gzip compression program (file name *.gz).

These data have been compressed using gzip version 1.2.4 and the high compression (-9) option

(Copyright (C) 1992-1993 Jean-loup Gailly). Gzip (GNU zip) uses the Lempel-Ziv algorithm (Welch,

1994) used in the zip and PKZIP programs. The compressed files may be uncompressed using gzip

(-d option) or gunzip. Gzip is available from many Web sites (for example, ftp site

prep.ai.mit.edu/pub/gnu/gzip-*.*) for a variety of operating systems in both executable and source

code form. Versions of the decompression software for various systems are included on the

CD-ROMs.

9. Data Manipulations

9.1 Formulae

The original data were acquired as ARC/INFO export files, one file per 10-km x 10-km area. The

data were imported into ARC, and attributes of the coverage polygons were manipulated within AML

scripts to produce new attributes. The new attributes were used as lookup tables for gridding the data,

and the separate maps were then mosaicked together into one map for each layer/attribute. The relevant

attributes (items) associated with each polygon in the vector data are as follows:

Page 8
The

Item Description

SPI0 Primary Species #i (one of 13 possible tree species)

SPII Primary Species #2 (same as SPI0)

SPI2 Primary Species #3 (same as SPI0)

SP20 Secondary Species #i (same as SPI0)

HGT Height Class (one of 5 classes in 5-m intervals)

D Density (crown closure, see below)

YOO Decadal Year of Stand Origin

MLEVEL Management Level (12 rarely used codes for nonforested polygons)

SYR Year of Source (year source info. for a polygon was obtained)

YSP Year of Silvicultural Activity (also rarely used)

R1 Regenerating Species 1 (as in SPI0, but may not be tree species)

DIST Disturbance Type (cut-over or partial cut, by season, or burn-over)

DYR Year of Disturbance

NP Nonproductive Type (codes to identify all nonforested polygons)

data layers created for this product were derived from the above attributes as follows:

Raster Layer Input Vector Items

COVER SA, SPI0, SPII, SPI2, SP20, MLEVEL, RI, DIST, NP

CROWN CLOSURE D

HEIGHT HGT

YEAR YOO, YSP, DIST, SA, SYR, DYR NP

9.1.1 Derivation Techniques and Algorithms

The species association data use the items listed above to select one of the 18 species associations

as defined by SERM, who provided the data. The minimum size for homogeneous forest stands varies

from 1-4 hectares depending upon the size (HGT) and economic value of the species.

The crown closure data were created using the D item within the coverages. This item is the

average percent crown closure of the forest stand and is assigned to one of four classes. The

boundaries of these classes are given in the table in Section 8.2. Values for item D exist only for

forested polygons.

The height class data were created from the HGT item within the coverages. The average height of

all living trees in the main canopy of the stand is assigned to one of five height classes. The limits of

the height classes are given in Section 8.2. Values for item HGT exist only for forested polygons.

The decadal year of origin or disturbance data were derived from a combination of the items listed

above. In the table in Section 8.2, year of silvicultural treatment and year of disturbance are coded

similarly. The ages of productive polygons were assigned to decadal classes. When ages overlap two

or more classes, the older class is usually chosen. Values for the year-associated items exist only for

forested or disturbed polygons.

9.2 Data Processing Sequence

9.2.1 Processing Steps

Most of the following processing steps were performed in ARC/INFO.

• New attribute items were added to the attribute files of each coverage to store the value that

would represent cover, crown closure, and year of stand origin

• HGT was already a numeric item and could be used directly as a lookup table for gridding the

height layer.

• Crown closure was not numeric, but levels were easily converted to a numeric item that was

used to grid the height layer.

• New values were assigned to the new cover item using the SERM definition of species

association, which assigns one of 18 common boreal associations from the many possible

10.2 Quality Assessment

10.2.1 Data Validation by Source

Unknown.

10.2.2 Confidence Level/Accuracy Judgment

The accuracy of the gridding procedure is high. Some consideration should be given to the scale of

the data and what will be inferred from it.

10.2.3 Measurement Error for Parameters

Unknown.

10.2.4 Additional Quality Assessments

None.

Page 10
10.2.5 Data Verification by Data Center

Each gridded image was checked visually to make sure that the gridding procedure assigned a

digital number (DN) to each attribute value. The data were also checked for gaps of "no data" along the

seams of the 10-kin x 10-km coverages used to compile this product.

1 1. Notes

11.1 Limitations of the Data

BORIS acquired these data in 1993; therefore, areas subjected to logging activity or other

disturbance, such as fire, will appear much different today as compared to the forest cover data.

11.2 Known Problems with the Data

None.

11.3 Usage Guidance

Saskatchewan Parks and Renewable Resources does not accept any liability for decisions or action

taken on the basis of these data.

Before uncompressing the Gzip files on CD-ROM, be sure that you have enough disk space to

hold the uncompressed data files. Then use the appropriate decompression program provided on the

CD-ROM for your specific system.

11.4 Other Relevant Information

Saskatchewan Parks and Renewable Resources also maintains stand and stock tables, 3P plots,

and possibly some permanent sample plots in this area. Aerial photographic prints and negatives are

also available. Contact the agency directly if you are interested in such information or if you wish to

acquire those data.

12. Application of the Data Set

This data set would provide good reference information for assessing spectral image data classification

techniques over the area and serve as an initial baseline data set for analyzing land cover and vegetation

change.

None.

13. Future Modifications and Plans

14. Software

14.1 Software Description

The Environmental Systems Research Institute (ESRI) ARC/INFO (Version 7.0) package was

used to perform the data manipulation and processing. Questions about the software should be directed

to ESRI. Gzip (GNU zip) uses the Lempel-Ziv algorithm (Welch, 1994) used in the zip and PKZIP

commands.

13. ABSTRACT (Maximum 200 words)

This data set, originally provided as vector polygons with attributes, has been processed by BORIS

staff to provide raster files that can be used for modeling or for comparison purposes. The original

data were received as ARC/INFO coverages or as export files from SERM. The data include information on forest parameters for the BOREAS SSA-MSA. Most of the data used for this product were

acquired by BORIS in 1993; the maps were produced from aerial photography taken as recently as

1988. The data are stored in binary, image format files.
