Digital Elevation and Surface Models

Value Added Products


We provide digital elevation data at very high resolutions down to 0.5 m spatial resolution. We create this dense elevation information using state-of-the-art photogrammetric dense point matching algorithms on very high-resolution satellite imagery. Furthermore, we provide seamless land-water 3D Digital Terrain Model (DTM) at very high spatial resolution, tuned for hydrological purposes, including bathymetry information of the first meters of a targeted water body.

Advantages at a glance:

  • Reduce or avoid time intensive on-site data collections.
  • Access up-to to-date spatial data.
  • Access data for remote or inaccessible locations.


What are the vertical and horizontal uncertainties of EOMAP’s DEM?
Typically, the absolute vertical and horizontal uncertainties are 3 m LE90/CE90. The actual vertical accuracy is depending on the environment (e.g. the presence of tall buildings and dense vegetation). In an open environment with moderate vegetation density or rural landscapes, the expected accuracies are usually well below 2m up to 1m LE90.

Can I access the satellite image data corrected for terrain impacts together with the delivery of the DEM?
Yes, orthorectified images are provided without additional cost on request.
