WV Digital Elevation Models (USGS 10-meter)
The 7.5-minute digital elevation model (DEM) data are digital representations of cartographic information in a raster form. The DEMs consists of an array of elevations for ground positions at regularly spaced 10-meter intervals. DEMs can be used as source data for digital orthophotos, and for earth science analysis as layers in geographic information systems. DEMs can also serve as tools for volumetric analysis, for site location of towers, or for drainage basin delineation. Originator is the U.S. Geological Survey. These Level 2 DEMs were generated from (1) 1:24,000-scale hypsography digital line graph (DLG) data or from (2) vector data derived from scanned raster files of USGS 1:24.000-scale separates.
