Dataset
LiDAR based Digital Terrain Model (DTM) data for South West England

This resource is made available under the terms of the Open Government Licence

This is a high resolution spatial dataset of Digital Terrain Model (DTM) data in South West England. The DTM along with a Digital Surface Model (DSM) cover an area of 9424 km2 that includes all the land west of Exmouth (i.e. west of circa 3 degrees 21 minutes West). The DTM represents the topographic model (height) of the bare earth. The dataset is a part of outcomes from the Centre for Ecology & Hydrology South West (SW) Project. There is also a Digital Surface Model (DSM) dataset covering the same areas available from the SW project.

Quality

Lineage
The British Antarctic Survey (BAS) acquired a new high resolution (circa 1 point/meter) and high accuracy (25 cm vertical) LiDAR dataset over Cornwall and Devon during the month of July and August 2013 for the Tellus South West project. The conversion of the raw LiDAR data into the digital terrain and surface model was carried out by the Environment Agency (contract). The spatial dataset consists of 2 cm height layers representing the terrain and surface height respectively at a spatial resolution of 1 m (grid cell) and an average height accuracy of 25 cm. The data is available as individual files representing sections of Ordnance Survey tiles in ESRI grid format (e.g. SX37ne; SX37nw; SX37se; SX37sw).
