DEM

Digital Elevation Model (DEM), also known as Digital Terrain Model (DTM), is a digital view of Earth’s topography used by the U.S. Geological Survey (USGS). This model uses the raster data format to create 3D images or colorized maps to display elevation.


The map shown is a Digital Elevation Model (DEM) Map of Crater Lake National Park. This particular DEM uses 3D imagery to show the elevation in the National Park. The bottom right image is a DRG of Crater Lake.
