Elevation 4
The models come in two formats: Digital Surface Model (DSM; a model of the ground that includes both ground and above ground features as buildings, vegetation, etc.) or Digital Terrain Model (DTM; representing the bare Earth elevation, vegetation and man-made objects removed). In addition to the elevation information, you also receive the original Pleiades imagery used to create it.
