This accurate digital elevation data is produced by Light Detection and Ranging (LiDAR), an airborne laser mapping technique. Datasets contain either a 'bare earth' Digital Terrain Model where vegetation and other surface features have been identified and removed; or a Digital Surface Model that includes surface objects depending on which product is ordered. Both datasets are available at four resolutions: 25cm, 50cm, 1m and 2m.

Who is this data for?
