Raw Landsat 4/5 data covering the UK were acquired from Infoterra by the Landmap project. Landmap subsequently orthorectified and mosaiced the images. Two types of image data from the satellite are available for the UK from 1988 to 1992: MultiSpectral Scanner (MSS) and Thematic Mapper (TM). Landsat 4 and 5 carry both the MSS and the TM sensors; however, routine collection of MSS data was terminated in late 1992. The MSS and TM sensors primarily detect reflected radiation from the Earth's surface in the visible and near-infrared (IR) wavelengths, but the TM sensor with its seven spectral bands provides more radiometric information than the MSS sensor. The Landsat Program is one of the longest running programmes for image acquisition from space, first launched in 1972 the program is managed between the U.S. Geological Survey (USGS) and NASA. Eight satellites have so far been launched, the most recent being Landsat 8, on February 11th, 2013. Landsat satellite imagery offers a unique resource for global change research and applications in agriculture, geology, forestry, regional planning, education, and national security. 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. When using these data please also add the following copyright statement: Original Landsat 4 & 5 Landsat data copyright NOAA. Distributed by CHEST under licence from Infoterra International.

Light Detection and Ranging (LiDAR) data was collected by The Geoinformation Group using LiDAR-equipped survey aircraft for the main urban conurbations of England and Wales (including London, Manchester, Birmingham, Liverpool, Newcastle, Edinburgh and Glasgow) as part of the Cities Revealed project, and made available through the Landmap service. The GeoInformation Group (TGG) has processed the data so that they are available as Digital Terrain Models (ground surface only) and Digital Surface/Elevation Models (the ground and all features on it), both geographic databases with height and surface measurement information in the form of regular grids with intervals of 1 or 2 m. In addition, some First Pass and Last Pass data are available. The First Pass data provides height values for the top of the canopy (i.e. buildings, trees etc.) while the Last Pulse data provides height values for the bottom of the canopy and provides information about the shape of the terrain. The data are available in img format. 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. When using the data please also add the following copyright statement: Cities Revealed © The GeoInformation Group yyyy

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.

A 2m resolution Digital Surface Model (DSM) for Scotland and Wales photogrammetrically derived from aerial photography by GetMapping and acquired by the Landmap project. 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. A DSM is a digital model of a terrain's surface and represents the earth's surface and includes all objects on it.
