This block provides streamed high-resolution elevation data acquired on a global basis. The datasets are available as a digital terrain model (DTM) and digital surface model (DSM).
- The DSM is hydro-enforced and includes surface elevations from terrain, vegetation and cultural features (buildings, roads).
- The DTM is hydro-enforced and includes the bare earth, where surface features (buildings, vegetation etc.) have been removed.
The datasets are available worldwide. Please note that the coverage for DSM and DTM can differ.
