Digital Terrain Model LiDAR data from Environment Agency and Natural Resources Wales for England and Wales plus data Scotland central belt
DTM data provides a 3D representation of the 'bare-earth' surface (i.e. without human-made features with the exception of dams, breakwaters, bridge revetments and other permanent earthworks which are considered to be part of the bare earth surface). A DTM can be paired with a DSM to derive height information regarding objects on the surface.
The data is referenced to Ordnance Survey Newlyn with a vertical accuracy of /-15cm RMSE. It is a composite of flown years and all years within a customer area of interest will be supplied. It is available in a variety of formats as follows:
- Contours in SHP, DWG - Point Cloud in ASC, XYZ, DXF
DTM data is particularly useful in urban planning, flood/disaster management and management of vegetation. For areas over 100km2, please contact Emapsite Customer Services.
