National Atlas of the United States 200506 Nation.DBO.State_Boundaries Reston, VA National Atlas of the United States withheld Nation.DBO.State_Boundaries vector digital data This map layer portrays the State boundaries of the United States, and the boundaries of Puerto Rico and the U.S. Virgin Islands. The map layer was created by extracting the State boundary polygons 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 coverage. This is an updated version of the June 2002 map layer; the date when each State was admitted to the United States was added. 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. en 1972 2005 REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.

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. These DLG files were updated in 1997. Using Arc/INFO software, the DLG optional format files were converted to Arc/INFO coverages using the DLGARC command. Only State political boundaries and attribute information were extracted for inclusion. The file was compared to ATLAS-HY98. State boundary lines that crossed open water were excluded for graphic purposes, and polygons that represented islands were attributed with the appropriate State 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. withheld withheld 1998 withheld The spatial features in ATLAS-STATES98 were compared to ATLAS-HY9903 and modified where necessary.
