Hydrographic Features of the United States
Entry ID: UTC_hydrography

[ Update this Record ]

Summary
Abstract: The data set portrays the polygon and line water features of the United States,
Puerto Rico, and the U.S. Virgin Islands. The file was produced by joining the
individual State hydrographic layers from the 1:2,000,000- scale Digital Line
Graph (DLG) data produced by the USGS. This is a revised version of the March
1999 data set.

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.
