DEMs are used to support a wide range of geographic information system (GIS) applications, including: surface hydrologic modeling, slope and aspect determination, viewshed analysis, fire modeling, contouring, transportation route planning, and profile generation. DEMs are also used to rectify aerial photography in the production of Digital Orthophoto Quads (DOQs)
10 Meter Digital Elevation Model (DEM) for the HJ Andrews Experimental Forest. A Digital Elevation Model (DEM) is a digital data file containing an array of elevation information over a portion of the earth's surface. This array is developed using information extracted from digitized elevation contours from PBS maps. A deatiled description of USGS DEMs can be found at http://rockyweb.cr.usgs.gov/elevation/dpi_dem.html as well as a users guide at ftp://mapping.usgs.gov/pub/ti/DEM/demguide/dugdem.txt.
