NEXTMap Britain 5m DSM data

Promap provides the industry benchmark for elevation data, accuracy and affordability with NEXTMap Britain's high density topographical data, covering England, Wales and Scotland.

Using airborne RADAR technology the ground surface has been modelled in detail with elevation points provided every five meters. The measurements are derived from the return signals received that bounce off the first surface they strike, making the DSM a representation of any object large enough to be resolved. These include buildings, vegetation, and roads, as well as natural terrain features.
