Bluesky 5m resolution Digital Terrain Model (DTM) for England and Wales
A Digital Terrain Model (DTM) for most of England and Wales provided by Bluesky and made available via the Landmap service, at 5m resolution. The 5m DTM is a photogrammetrically derived product from stereo aerial photography collected between 1999 and 2008. The aerial photography was captured at a resolution of between 10cm and 25cm. A digital elevation model is a digital model or 3D representation of a terrain's surface and, in contrast to a Digital Surface Model (DSM), represents the bare ground surface without any objects like plants and buildings. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK, part of which was elevation data. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.
