Provided by our partner, Airbus Defence and Space, LiDAR Data (Light Detection and Ranging) is high accuracy, high resolution elevation data derived from airborne sources. A laser is used to measure the distance between the aircraft and ground and between the aircraft and the vegetation canopy or building tops. For major towns and cities, LiDAR data is available at 1m intervals, provided in the form of a regular grid of points with overall positional accuracy of +/- 0.5m RMSE and +/- 0.25m vertical accuracy.

LiDAR Data is available for both terrain (DTM) and Surface (DSM) heights:
- Digital Terrain Model (DTM) – is a topographic model of the bare earth that has had vegetation, buildings, and other cultural features digitally removed, enabling users to infer terrain characteristics possibly hidden in the DSM.
- Digital Surface Model (DSM) – is a topographic model of the earth’s surface that includes buildings, vegetation, roads, and natural terrain features. The key benefit of the DSM is that it provides a geometrically correct base map.
- For rural areas where LiDAR is not available, 5m Digital Terrain Model (DTM) data can be provided with overall positional accuracy of +/-1m RMSE and overall vertical accuracy of +/-1.5m RMSE.
- Formats available include ASCII Grid, ESRI ASCII Grid, ESRI BINARY Grid, AutoCAD DWG or DXF.
Depending on the age and functionality, some CAD software will not understand the height data attribution. Contact our Service Centre team for data translations, e.g. 5m DTM translated to a DWG CAD Contour layer.
