The NASA STI Program Office ... in Profile

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.

TECHNICAL TRANSLATION.

English-language translations of foreign scientific and technical material pertinent to NASA's

mission.

Specialized services that complement the STI

Program Office's diverse offerings include creating custom thesauri, building customized databases, organizing and publishing research results...

even providing videos.

1. Data Set Overview

1.1 Data Set Identification

Vector Topographic Map Data over the BOREAS NSA and SSA in SIF Format

1.2 Data Set Introduction

This data set was acquired by BOReal Ecosystem-Atmosphere Study (BOREAS) Information

System (BORIS) staff from Geomatics Canada. The data exist as single or pairs of files for individual

map sheets from the National Topographic Series (NTS). The data in the files were received in

Standard Interchange Format (SIF).

1.3 Objective/Purpose

These data are provided as part of the BOREAS Staff Science Geographic Information System

(GIS) Data Collection Program, which included the collection of pertinent map data, in both hardcopy

and digital form. The purpose of this data-gathering effort was to provide the user with elevation

contours of the Modeling Sub-Areas (MSAs). These data could be used to create Digital Elevation

Models (DEMs) and to construct other topographic map features of the MSAs.

Page 1
1.4 Summary of Parameters

There are feature codes located in the summary statistics (.ss) or description (.map) file for each

map. These vary by map but contain, in addition to codes for elevation contours, codes for those map

elements common to most topographic maps, such as water bodies, watercourses, trails, roads, and

point information. For map elements corresponding to the contour feature codes, the elevation of the

contour (meters above mean sea level) and North American Datum of 1983 (NAD83) Universal

Transverse Mercator (UTM) coordinate pairs (easting and northing) along the contour are available.

1.5 Discussion

These data were given to BOREAS staff in various versions of SIF. Source code provided by the

Hydrology (HYD)-08 science team was modified to read the contour data from various files. This code

(undocumented) is provided as part of this data set. The input data were understood to be in a standard

format, but they were not standard in terms of the software's ability to consistently read all of the data

files. BORIS staff has not been able to obtain a format document or acquire commercial software for

reading SIF, though such software does exist. BORIS staff used the modified HYD-08 source code to

reformat the data into ARC GENERATE line format, which is strings of x, y coordinate pairs, with

each string (line) being associated with an elevation value. For more detailed information regarding the

ARC GENERATE format and data set, refer to the documentation for the BOREAS Vector Contours

for the NSA and SSA in ARC/INFO Generate Format data.

7.3.2 Variable Description/Definition

The only features about which BORIS personnel have any substantial information are the elevation

contours. Note that although feature codes 9231 and 9234 correspond to the intermediate (CONTOUR

OTH COL INTMED DEF) and index (CONTOUR OTH COL NDX DEF) elevation contours in this

map sheet, different feature code numbers represent the same features in other map sheets.

• CONTOUR OTH COL INTMED DEF: An elevation above mean sea level (the vertical

distance between a plane at mean sea level and a parallel plane intersecting this point) and

series of geographic coordinate pairs that define the points along the given intermediate

elevation contour.

• CONTOUR OTH COL NDX DEF: An elevation above mean sea level (the vertical distance

between a plane at mean sea level and a parallel plane intersecting this point) and series of

geographic coordinate pairs that define the points along the given index elevation contour.

Note that depending on the map sheet, the geographic coordinates are given in either the NAD27 or the

NAD83 datum, where:

• NAD27 UTM coordinate pairs are the NAD27-based UTM Easting and Northing coordinate

pairs that define the geographic locations over which the given contour exists.

• NAD83 UTM coordinate pairs are the NAD83-based UTM casting and northing coordinate

pairs that define the geographic locations over which the given contour exists.

7.3.3 Unit of Measurement

The measurement units known by BORIS personnel are:

• CONTOUR OTH COL INTMED DEF: meters above mean sea level

• CONTOUR OTH COL NDX DEF: meters above mean sea level.

• NAD27 UTM coordinate pairs: NAD27 UTM meters.

• NAD83 UTM coordinate pairs: NAD83 UTM meters.

8.1 Data Granularity

The smallest amount of data obtainable is all of the 1:50,000-scale data and all of the

1:250,000-scale data.

8.2 Data Format(s)

Two tar files are associated with this data set: one that contains the 1:50,000 map files and one that

contains the 1:250,000 map files. Each of the map files has been Unix compressed; to expand a given

map file, use the Unix uncompress command. The NSA map file names begin with 73, and the SSA

map file names begin with 63 or 64. The individual map files contained in the l:50,000-scale tar file

The available information for each map is generally (but not always) contained in two files. The file

names correspond to the NTS map identifiers (i.e., 73109 or 73I for the 1:50,000 and 1:250,000

scales, respectively). Vector position data have one of three file extensions, .sif, .k2a, or .k8a, and

map statistics/descriptions have one of two file extensions, .ss or .map. Although the features

contained in each map are fairly consistent, the features and statistics do vary with location and map

complexity. The following are the file extensions that can be found as part of this data set, although

little is known about these designations:

10. Errors

10.1 Sources of Error

One source of error is the digitizing process used to create the contours from the map sheets. It is

not known whether the maps were hand digitized or if a more automated scanning process was used to

digitize the contours.

10.2 Quality Assessment

10.2.4 Additional Quality Assessments

None.

Page 10
10.2.5 Data Verification by Data Center

Quantitative estimates were not made for any of the features in the files. Visual assessment of the

contour data showed the spacing to be appropriate for the 1:50,000 scale (i.e., there was no noticeable

jaggedness or discontinuities along the contours). The 1:250,000-scale data were not checked. After

extracting the data into the ARC/INFO Generate files, BORIS staff plotted the contour data and

visually reviewed the data with the 1:50,000 hardcopy maps. No anomalies or errors in the contour

data were detected in this review.

1 1. Notes

11.1 Limitations of the Data

Because the data have a 25-ft contour interval, variations in the terrain that are smaller than 25 ft

may not be detectable. The user should not expect to see terrain detail such as small berms or other

minor topographic relief. Even less topographic detail (variation under 100 ft) is available from the

1:250,000-scale maps with their 100-ft contour interval.

11.2 Known Problems with the Data

The NSA maps from which these Global Positioning System (GPS) data were derived were found

to be in disagreement with differentially corrected GPS coordinates gathered by BOREAS by about

150 m. The error did not appear to be systematic. The SSA maps have a higher degree of accuracy

(about 45 m) when compared to GPS.

11.3 Usage Guidance

If these data are going to be used to create a DEM, the various vector files should be edgematched

to create seamless contours that do not have discontinuities at the map boundaries.

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

the uncompressed data files.

11.4 Other Relevant Information

None.

12. Application of the Data Set

This data set can be used to create a gridded DEM of the area of interest. It could also be used for

graphical purposes, as an overlay along with other vector layers.

13. Future Modifications and Plans

None.

14. Software

14.1 Software Description

The software to read the SIF data was originally produced by an unknown source. The BOREAS

HYD-08 team provided source code that could read some of the SIF files. The software reads the input

file and extracts certain features based on feature codes that are supplied by the user. The software is

written in C and is operational on Unix workstations at GSFC.

14.2 Software Access

The software is included on the data tape.

Page 11
15. Data Access

The vector topographic map data are available from the Earth Observing System Data and Information

System (EOSDIS) Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center

(DAAC).
