Abstract:
These coverages are 1:5,000,000-scale boundary files of specific U.S.
regions and territories by state equivalent code (FIPS) and the 50 U.S.
States. The boundary files are selected generalized extracts from the
Census Bureau's TIGER geographic database designed for use in a Geographic
Information System (GIS) or similar mapping system. They have been developed
for various internal Census Bureau projects and have been made available
here to the general public on an "as is" basis.
Purpose:
This dataset is best used as a base map for state- and regional -level
(not national) data and analysis.
Supplemental_Information:
Procedures_Used:
Geography extracted from the Census Bureau's TIGER database. Converted
to an ARC/INFO coverage (v. 7.1). The USPRVI_BND coverage was created
by unioning the Conterminous U.S., Puerto Rico, and U.S. Virgin Islands
files together in ARC/INFO.

- Use_Constraints:
To meet the Census Bureau's needs for small-scale (i.e., large-area)
mapping, these boundary files have been thinned and/or generalized.
This means that the number of spatial data coordinates has been reduced
to decrease file size and permit faster data processing. During the
thinning/generalizing processes, an effort was made to maintain the
general shape of the geographic entity, however, because of the nature
of the processes used, these boundary files are not spatially accurate
enough for legal reference and are not recommended for navigation purposes.

in a boundary coverage of the conterminous U.S., Puerto Rico, and the
U.S. Virgin Islands - USPRVI_BND.
