Description:
Abstract:
This data set is an ARC/INFO shapefile that portrays the
federally owned land polygon features of the United States.
The data set was created by extracting federal land polygon
features from the individual 1:2,000,000-scale state
boundary DLG files produced by the U.S. Geological Survey.
These files were then paneled into a single coverage
Purpose:
These data were created to serve as a layer for the
National Atlas of the United States of America
Supplemental Information:
Revisions: 1) 3/22/98 - Corrected topological problems
along state lines, corrected coding errors (Lake Tahoe),
and added Escalante national monument. State attribute
codes were removed. Fort Frederica, GA was deleted because
it was below the minimum mapping area of 640 acres. 2)
6/17/98 - Corrected URL for Glacier National Park. 3)
6/29/98 - Corrected ellipsoid name from WGS84 to GRS1980
and changed flattening ratio

Data Quality Information
Section Index
Attribute Accuracy:
Attribute Accuracy Report:
Accuracy at the DLG level was tested by one or more of the
following methods: - manual comparison of the source with
hard copy plots. - symbolized display of the digital line
graph on an interactive computer graphic system. - Selected
attributes that could not be visually verified on plots or
on screen were interactively queried and verified on
screen. As the DLG files were directly converted to
ARC/INFO coverages, attributes have not been checked in the
ARC/INFO format
Logical Consistency Report:
Using ESRI's ARC/INFO GIS software, the data set was
checked for label errors, dangling nodes, and
intersections. Polygon topology was built for the data set
using the ""BUILD"" command
Completeness Report:
Data completeness generally reflects the content of the
original DLG file.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
In DLG format, files underwent comparison to a graphic

Process Step:
Process Description:
This file was originally digitized by the National Mapping
Division based on the sectional maps contained in 'The
National Atlas of the United States of America' published
by the USGS in 1970. The sectional maps were updated during
1978-1981 and digitized in the early 1980's. The data were
updated in 1995 using 1:1,000,000-scale and
1:2,000,000-scale BLM state base maps. These data were
published on CD-ROM in 1995. Using ARC/INFO software, the
DLG optional format files were converted to ARC/INFO
coverages using the DLGARC command. Only federal land
polygons and attribute information were extracted for
inclusion. The sections were then paneled together using
the ARC/INFO command APPEND. ""Slivers"" created during the
append process were identified and deleted using the
ELIMINATE command. The attribute AGBUR was added for
plotting purposed. The codes used are: BIA (Bureau of
Indian Affairs), BOR (Bureau of Reclamation), BLM (Bureau
of Land Management), DOD (Dept. of Defense), FS (Forest
Service), FWS (Fish and Wildlife Service), NPS (National
Park Service), TVA (Tennessee Valley Authority), and OTHER.
In 1998, topological errors introduced when the state files
were paneled were corrected. Grand Staircase-Escalante
National Monument was added. Coding of Lake Tahoe was
corrected, and Fort Frederica, GA was deleted because it
was smaller than the minimum area of 640 acres. The data
were converted to shapefile format for use in National
Atlas applications and for distribution to the public
