A Digital Terrain Model (DTM) is a
digital file consisting of a grid of regularly spaced points of known height
which, when used with other digital data such as maps or orthophotographs, can
provide a 3D image of the land surface. 10m and 50m DTM’s are available. This is a large dataset and will take sometime to download. Please be patient. By
download or use of this dataset you agree to abide by the LPS Open
Government Data Licence.
