Federally Owned Land Polygon Features of the United StatesEntry ID: UTC_landpolygonfeatures
Abstract: This data set consists of 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 Digital Line Graph (DLG)
files produced by the U.S. Geological Survey. These files were then appended
into a single coverage. This is a revised version of the June 1998 data set.
There may be private in holdings within the boundaries of Federal Lands in this
These data are intended for geographic display and analysis at the national
level, and for large regional areas. The data should be displayed and analyzed
at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed
by the U.S. Geological Survey in the use of these data.

Quality The accuracy of the Digital Line Graphs was tested by one or more of the
following methods: 1) manual comparison of the source with hard copy plots, 2)
symbolized display of the digital line graph on an interactive computer graphic
system, 3) selected attributes that could not be visually verified on plots or
on screen were ... interactively queried and verified on screen. The DLG files
were directly converted to Arc/INFO coverages, so attributes have not been
checked in the Arc/INFO format.
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.
This data set includes federal land polygon features for all 50 of the United
States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.
The minimum map resolution is 640 acres or one square mile. Generally, features
under this size are not shown.
