Digital Terrain Model (DTM)

A Digital Terrain Model (DTM) represents the shape of the bare earth as a georeferenced elevation model. Unlike a Digital Surface Model (DSM), a DTM contains only the ground surface – objects such as vegetation, buildings, vehicles, or technical structures are classified and removed depending on the input data. Any gaps created by this process can be interpolated to produce a continuous model. If you prefer no interpolation, we can deliver the model accordingly.

We deliver the DTM – like the DSM – as vector or raster data in suitable formats and at the required resolution or point density, so it can be processed reliably in external software.

Common vector formats:
*.txt / *.xyz
*.dxf
*.asc (ASCII)

Common raster formats:
*.tif
*.jpg
