Digital Surface Model Overlay

Example of the DSM Overlay

The Digital Surface Model (DSM) Overlay is a Grid Overlay that displays the elevation model, the height of the terrain plus the building height. This means that if you add an extra floor to a building, the surface elevation model (DSM) will be automatically updated. This method also applies when you upload more detailed 3D building models. For instance, the model of a landmark church will be integrated into the new DSM. Enabling you to conduct advanced heat stress or shadow analysis simulations.

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 combined height of the terrain and any building at the selected location.

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

Additional information displayed in hover panel

Digital Surface Model: Hover panel displays additional information about the height of the terrain and the building that is located on it

Clicking a location on the map opens a hover panel with details about the terrain and building height.
