Digital Surface Model (DSM) refers to the digital representation of height of the surface including the buildings, bridges, trees etc. Compared to a DEM, a DSM contains more elevation information for buildings, bridges, forests and other surface object that don’t exist in the DEM. DSM is based on DEM and further covers the elevation of surface information other than the ground.
