Elevation models (DEMs)

Two types of elevation models are available: Digital Surface Models (DSM) and Digital Terrain Models (DTM). A DSM represents the earth’s surface including all objects on it (such as trees and buildings). A DTM shows the bare ground surface with these objects removed.

Geoserve is a distributor for all major DEM providers, including Airbus, Intermap, RESTEC and Vricon. Below table only shows a selection of available elevation models. Please contact Geoserve for other options.
