DSM — Digital Surface Model

A 3D model of everything visible from above — ground, trees, buildings, infrastructure, vehicles. Built from stereo or tri-stereo captures.

Fig. 1 DSM (Digital Surface Model) records the elevation of everything visible from above — canopy top, rooftops, infrastructure. Cross-section view shows how DSM height tracks the first surface the satellite sees, not the ground beneath.

A DSM is a raster where every pixel value is the elevation of the highest surface at that location — the top of the canopy if it's forest, the rooftop if it's a building, the ground if it's bare. Built from stereo or tri-stereo satellite captures.

When to use

Anything where the surface features matter — urban planning, solar siting, line-of-sight analysis, volumetrics on stockpiles, telecom propagation modelling.

Pricing

Priced separately from imagery, case-by-case depending on area and acquisition geometry. Requires the source sensor to support stereo or tri-stereo capture.
