A data block that 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).
See this block on the marketplace.
- 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.
- K-Means Clustering
- RF Viewshed
The datasets are available worldwide. Please note that the coverage for DSM and DTM can differ.
