USGS DEM Maps

These maps are based on the USGS digital elevation (DEM) database which is available via FTP or CD-ROM. The data was read in and decoded into a WXP grid file and contoured with WXP's contour program. Some of the maps are also overlaid with state, county outlines, roads, and rivers. This information is derived from the USGS digital line graph (DLG) database.
