The DSM (Digital Surface Model) is a 2.5 D model of the mapped area. It can be exported as two different types of files:
- Raster .geotiff.
- Vector point cloud (.xyz, .las, .laz).
Each pixel of the raster geotiff file and each point of the vector point cloud contain (X,Y,Z) information. They do not contain color information.

For each (X,Y) position, the DSM has only 1 Z value (the altitude of the highest point for this (X,Y) position). This is why it is considered to be a 2.5D model.
