Why use Satellite-Derived DEMs

Generate accurate elevation data from stereo satellite imagery without ground surveys or aerial capture.

0.5m

High-Resolution Data

Generate Digital Surface Models (DSMs) and Digital Terrain Models (DTMs) at resolutions from 0.5m to 5m, ideal for site planning, slope analysis and 3D visualisation applications.

Global

Anywhere Access

Obtain elevation data for any location worldwide without the need for ground crews, aircraft, or permits. Ideal for remote and inaccessible areas.

DSM + DTM

Surface & Terrain Models

Receive both Digital Surface Models and bare-earth Digital Terrain Models processed from the same source data.

  1. [A]

    DSM & DTM Products

    We provide Digital Surface Models (DSM), capturing all surface features including vegetation, buildings and infrastructure, as well as Digital Terrain Models (DTM), representing the bare-earth surface. Both products are generated from stereo satellite imagery using advanced photogrammetric processing.
