Comparison: Surface Model & Terrain Model

3D terrain data comparison:

Intermap's NEXTMap digital surface model (DSM) is a first-reflective-surface model that contains elevations of natural terrain features in addition to vegetation and cultural features such as buildings. It provides seamless, wide-area, and current terrain data so you can perform more accurate cross-border geospatial analyses in applications that require above-ground features, such line-of-sight, viewshed, telecommunications, and forestry.

Our NEXTMap digital terrain model (DTM) is a bare-earth model that contains elevations of natural terrain features such as barren ridge tops and river valleys. Elevations of vegetation and cultural features, such as buildings and roads, are digitally removed. It provides seamless, wide-area, and current terrain data so you can perform more accurate cross-border geospatial analyses in applications that require a bare-earth model, such as contour generation, base, geologic, and topographic mapping.
