NEXTMap Britain 5m Height 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.

DTM Height Data
As with DSM, elevation points provided every five meters, however, ground surface objects have been processed and removed to give a representation of the bare earth.



DSM Height Data
Using airborne RADAR technology the ground surface has been modelled in a 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.
