2000 County Boundaries: Map Layer Description File

This map layer portrays the 2000 county boundaries of the United States. County names and Federal Information Processing Standard (FIPS) codes are two significant pieces of information associated with every county polygon in this map layer. The County Boundaries map layer was compiled by the U.S. Geological Survey from a variety of sources.

Description:

Abstract:

This data set portrays the 2000 State and county boundaries of the United States, Puerto Rico, and the U.S. Virgin Islands. The data set 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 January 2002 data set.

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 U.S. Geological Survey 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.

Process_Description:

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.
