  • 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.

  • This is a web map service (WMS) of Digital Terrain Model (DTM) data in South West England at a 1m resolution. The DTM covers 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.

  • The elevation data collected by the Landmap project consist of a 5m resolution Digital Terrain Model (DTM) for England and Wales (Bluesky) and Scotland (GetMapping), a 2m resolution Digital Surface Model (DSM, equivalent to a DEM) for Wales and Scotland and 1m resolution LiDAR-derived DTMs and DSMs for cities of England and Scotland. 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. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

  • Hydrologically corrected digital terrain model (DTM) of Plynlimon catchments. The DTM was derived from digitised elevation data from scanned topographic maps.
