Digital Elevation and Terrain Models

Digital Elevation Models (DEM) represent the exact data on Earth's surface elevation except for objects of vegetation cover and anthropogenic objects.

Based on DEM, one can fast create a series of thematic maps of major morphometric indicators: hypsometrical map, steepness maps and slopes exposures, etc. Digital Terrain Models (DTM) contain information on the elevation of ground surface, including buildings, vegetation and other high-rise objects.


CRS & GIS “Terra” performs a complex of works to create digital elevation models and 3-D modeling. Also, the Company delivers global digital elevation models: WorldDEM, NextMap, AW3D, SRTM and AsterDEM.
