- Description:
-
- Abstract:
-
This map layer portrays the State and county boundaries of the United
States, Puerto Rico, and the U.S. Virgin Islands. The map layer was
created by extracting county 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 merged into a single
file. This is a revised version of the November 2004 map layer.
- Purpose:
-
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 National Atlas of the United States
in the use of these data.

- Process_Description:
- The 2MILBD data files were 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 again in the early 1990's by the USGS and published on CD-ROM in 1995 as State DLGs. Using Arc/INFO software, the updated DLG optional-format files were converted to Arc/INFO coverages using the DLGARC command. Only county boundaries and attribute information were extracted from the boundaries DLG layer for inclusion in this national coverage. The county boundary lines that crossed open water were excluded for graphic purposes and polygons that represented islands were attributed with the appropriate county information. The individual State coverages were then merged together using the Arc/INFO command MAPJOIN. "Slivers" created during the MAPJOIN process were identified and deleted using the ELIMINATE command. In 1998, the delineation of the boundary of Mojave County, AZ was corrected. Minor modifications were also made to boundaries in Alaska.

- The spatial features were compared against the National Atlas hydrography layer (ATLAS-HY9903) and modified where necessary. Incorrect attributes were corrected. Yellowstone County was deleted and the boundaries for Gallatin and Park Counties were adjusted to absorb the area of Yellowstone National Park. Puerto Rico and the U.S. Virgin Islands were added.

The boundary of Juneau Borough, Alaska was modified to include
approximately 61,000 acres of northern Admiralty Island. Data from
the Census Bureau's county boundary file of Alaska was extracted and
generalized to a scale of 1:2,000,000.
The boundary of Denver County, Colorado was modified to include the area occupied by Denver International Airport. Additional minor corrections were made to Denver County and Adams County. All corrections were made using data from the Census Bureau's county boundary file of Colorado.
Finally, county attribution was removed from the Niagara River between Lake Ontario and Lake Erie.

1) Navajo and Coconino in Arizona 2) Tuolumne and Mono in California 3) Lake and Chaffee in Colorado 4) Gulf and Franklin in Florida 5) Plaquemines Parish and Jefferson Parish in Louisiana 6) Mora and Taos in New Mexico 7) Otero and Chaves in New Mexico 8) Canovanas Municipio and Loiza Municipio in Puerto Rico 9) Tipton and Shelby in Tennesee 10) Loving and Winkler in Texas 11) Pecos and Terrell in Texas 12) Kerr and Bandera in Texas 13) Real and Bandera in Texas 14) San Patricio and Nueces in Texas 15) Sanpete and Jab in Utah 16) Harrisonburg City and Rockingham County in Virginia 17) Staunton City and Augusta County in Virginia 18) Lynchburg City and Campbell County in Virginia 19) Danville City and Pittsylvania County in Virginia
Numerous additional minor boundary adjustments were made throughout the country. In Puerto Rico, Florida Municipio was added and an offshore island was added to Ponce Municipio. A extra polygon within Vega Baja Municipio was merged with the rest of the municipio.An attribute containing the area in square miles for the county was added. It was calculated by summing values in the area field for each county, which is in square meters, and multiplying the results by 0.0000003681.
