Some examples of DEMs at 2m Resolution

Geoimage is able to provide its clients with 2m DEM products. These datasets are most suited to customers who require an accurate elevation product, but do not require the level of detail of a 1m DEM product.

The 2m DEM products are generated from VHR satellite stereo imagery. These datasets improve the accuracy of processes like image orthorectification. They can also be used within Project Planning/Concept Applications, Hydrological Modelling studies and 3D visualisation.

Stereo Imagery is available from the following VHR Satellites:

  • WorldView-1, 2 and 3
  • GeoEye-1, and
  • Pléiades
