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.

• TECHNICAL MEMORANDUM. Scientific

and technical findings that are preliminary or

of specialized interest, e.g., quick release

reports, working papers, and bibliographies

that contain minimal annotation. Does not

contain extensive analysis.

• CONTRACTOR REPORT. Scientific and

technical findings by NASA-sponsored

contractors and grantees.

CONFERENCE PUBLICATION. Collected

papers from scientific and technical

conferences, symposia, seminars, or other

meetings sponsored or cosponsored by NASA.

SPECIAL PUBLICATION. Scientific, technical, or historical information from NASA

programs, projects, and mission, often concerned with subjects having substantial public

interest.

SERM Forest Cover Data of Saskatchewan in Vector Format

Jaime Nickeson, Fern Gruszka

Summary

This data set was acquired as a general provincial scale vegetation cover map and an alternative to the

very detailed vector forest cover data available for the BOREAS SSA. The data set was prepared by

SERM-FBIU, and is a condensed forest cover type map of Saskatchewan at a scale of 1:1,000,000.

The date of the maps from which this data set was generated is unknown; it is estimated that the forest

cover maps were made in the mid-1980s.

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

the Gzip program. See Section 8.2 for details.

1. Data Set Overview

1.1 Data Set Identification

SERM Forest Cover Data of Saskatchewan in Vector Format

1.2 Data Set Introduction

The condensed forest cover type digital map of Saskatchewan is a product of the Saskatchewan

Environment and Resource Management, Forestry Branch - Inventory Unit (SERM-FBIU). This map

was generalized from SERM township maps of vegetation cover at an approximate scale of 1:63,000

(1 in. = 1 mile). The cover information was iteratively generalized until it was compiled on a

1:1,000,000-scale map base.

Page 1
1.3 Objective/Purpose

These data are provided as part of the BOReal Ecosystem-Atmosphere Study (BOREAS) Staff

Science Geographic Information System (GIS) Data Collection Programs, which included the

collection of all pertinent map data in the BOREAS area of interest in both hardcopy and digital form.

This data set was acquired as a general provincial scale vegetation cover map and an alternative to the

very detailed vector forest cover data available for the Southern Study Area (SSA).

1.4 Summary of Parameters

There are just two items associated with each forest cover type polygon in this data set. Forest

class (merchantable, nonmerchantable, other) and forest type. There are four merchantable and

nonmerchantable forest cover types and 10 types within the "other" forest class.

1.5 Discussion

The forest cover type data set of Saskatchewan at a scale of l: 1,000,000 provided by SERM-FBIU

is a generalized cover map of the forested region of the province. Little is known about this data set. It

has not been documented by SERM personnel, and they have since informed BOREAS staff of a data

set that has been produced more recently that should have a higher level of accuracy and precision.

Contact SERM directly regarding the updated product (Section 2.3).

3. Theory of Measurements

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

forested lands. 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. This map was produced as a generalization of this inventory.

5. Data Acquisition Methods

The forest cover type data set of Saskatchewan at a scale of 1:1,000,000 provided by SERM-FBIU is

a generalized cover map of the forested region of the province. The map was generalized from SERM

township maps of vegetation cover at an approximate scale of 1:63,000 (1 in. = 1 mile) in the Lambert

Polyconic projection. The information was iteratively generalized until it was compiled on a

1:1,000,000-scale map base, of unknown projection. Little detail is known about this data set, and

SERM has stated "[we] cannot overstate how dated and imprecise this product is." Nevertheless, the

data set is being made available because within BOREAS there are needs for coarse-scale information.

6.1 Data Notes

Unknown.

6.2 Field Notes

Unknown.

6. Observations

7. Data Description

7.1 Spatial Characteristics

7.1.1 Spatial Coverage

This data set covers the forested portion of the province of Saskatchewan. In ARC/INFO when

you DESCRIBE the coverage, this is what you will get:

COVERAGE BOUNDARY

Xmin = 7.479 Xmax = 30.013

Ymin = 5.105 Ymax = 27.117

The BOREAS Information System (BORIS) staff does not know what these units are, but guesses that

they might be inches from the digitizing table and that real-world coordinates were never entered for

this data set. On the hardcopy map of the data, it is apparent that the borders on the east and west are

the Saskatchewan provincial boundaries. The northern and southern boundaries are 57 and 52 degrees

latitude, respectively. The comers are given below; the Southeast comer coordinate was approximated.

Longitude Latitude

(degrees) (degrees)

Northwest ii0 57

Northwest 102 57

Southwest ii0 52

Southeast 101.6 52

7.1.2 Spatial Coverage Map

Not available.

7.1.3 Spatial Resolution

This is a very coarse and imprecise data set with limited available information associated with it. At

a scale of 1:1,000,000, gridding the data to a raster cell size of 1,000 m x, 1000 m would seem

appropriate.

Page 4
7.1.4 Projection

Theactualprojectionisunknown.A bestguesswould be that it is Lambert Conformal Conic under

the North American Datum of 1927 (NAD27). If one wishes to PROJECTDEFINE this coverage in

ARC/INFO, the following information would be useful:

NAD27 CNT

ist standard parallel: 50 degrees

2nd standard parallel: 58 degrees

Central Meridian: 115 degrees

Latitude of projection's origin:

False Easting (meters) : 0.0

False Northing (meters) : 0.0

50 minutes

i0 minutes

0 0 0

Our sources at SERM indicate that one could rubber sheet it to almost any projection and it would not

be significantly less accurate.

7.1.5 Grid Description

Not applicable.

7.2 Temporal Characteristics

7.2.1 Temporal Coverage

Most of the data used for this product were acquired by BORIS in 1993. The forest cover type data

set of Saskatchewan at a scale of 1:1,000,000 provided by SERM-FBIU is a generalized cover map of

the forested region of the province. This data set has not been documented by SERM, and little detail is

known about it, including creation date, other than the comment that it was created "many years ago."

SERM has informed BOREAS staff of a data set that has been produced more recently that should

have a higher level of accuracy and precision. Contact SERM directly regarding the acquisition of an

updated forest cover type product (Section 2.3).

7.2.2 Temporal Coverage Map

Not available.

7.2.3 Temporal Resolution

The original maps (1:12,500) are completely reinventoried by SERM personnel on a 10- to 20-year

cycle, except for disturbed areas, which are updated annually. The date of the maps this data set was

generated from is unknown. BOREAS staff's best guess is that it was generated from forest cover

maps made in the mid-1980s. One could possibly try to determine the approximate year by the

evidence or lack thereof for significant known fires.

7.3 Data Characteristics

7.3.1 Parameter/Variable

Polygon features with attributes. Each polygon has a CLASS and TYPE item associated with it in

addition to relative spatial information.

7.3.2 Variable Description/Definition

• forest cover class - described as either merchantable, unmerchantable, or other

• forest cover type - for merchantable and unmerchantable the type is one of the following:

• softwood jackpine

• softwood spruce

• hardwood

13. ABSTRACT (Maximum 200 words)

This data set was acquired as a general provincial scale vegetation cover map and an alternative to the

very detailed vector forest cover data available for the BOREAS SSA. The data set was prepared by
