A Digital Surface Model (DSM) represents the earth´s surface and includes all objects on it, such as houses, trees, tall buildings, etc.
All of our terrain modeling is done with the DSM format.
In contrast to a DSM, the Digital Terrain Model (DTM) represents the bare ground surface without any objects like plants and buildings.
The term Digital Elevation Model (DEM) is used as the generic term for DSMs and DTMs.
The different colors on the model represent different elevations. This can be especially helpful to property owners who need to know what the topography is like on their property.
On construction sites, this tool is very useful in determining if the ground is level across all segments of the property and can immediately inform the job foreman as to whether he needs to bring in more material, take material out or just move material from one spot to another to accomplish a level grade.
