Digital Terrain Model Overlay

Example of the DTM Overlay

The Digital Terrain Model (DTM) Overlay is a Grid Overlay that displays the elevation model, the height of the terrain. The Overlay is available to all Stakeholders when added to a project.

There exist two Heightmap Overlay types:

• Digital Terrain Model type: displays the height of the terrain at the selected location on the map.
• Digital Surface Model type: displays the height of the terrain and the height of the building that is located on the selected location on the map.

For more information on how terrain height is obtained in the Tygron Platform, see elevation model.
