Thermal imagery for selected areas of England was taken by a FLIR SC 6000 HS thermal camera mounted on a specially designed survey aircraft over the course of 2009 and 2010 by The GeoInformation Group (TGG) as part of the Cities Revealed project. The data were then acquired by the Landmap project. Positioning data were also recorded so that the thermal data could be accurately geolocated in post-processing. The thermal data were captured between 7pm to 11pm to avoid solar activity which would produce false readings and when most houses would be heated, in cold (less than 10C) dry weather so that the temperature differential between indoors and outdoors was maximum. The thermal camera has a resolution of <0.02C. 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, such as thermal imagery, 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.

The Building Class data provides detailed information about residential housing types including the house age and structural type. This information can be used for urban regeneration studies, crime monitoring, urban flooding and urban gardens. These data were collected by The GeoInformation Group (TGG), primarily through interpretation of high-resolution aerial photography, as part of the Cities Revealed project. The data were subsequently 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 buildings data.

UK coverage at 50cm to 1m resolution for various dates from the 1930s onwards including UK-wide post war surveys from 1946 to 1952, city, county and district wide databases with a variety of film and print archives also available. Small areas of France were also covered. Sources include R.A.F., U.S.A.F. and Luftwaffe. The data were acquired by the Landmap project from The GeoInformation Group's (TGG) Cities Revealed project. Created from original film where possible, sourced from several archives, this database represents the very best of RAF, Luftwaffe and USAF aerial photography flown during 1939 to 1952. Images were then mosaiced together to produce regional coverage for various areas. Close inspection of some of the images will show where the images were created using printed images as printed annotations are visible. While in other cases prints are visible on the margins of the original film shown.

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.

Aerial photography obtained from The Geoinformation Group's (TGG) Cities Revealed project, acquired by the Landmap project, is available for over 65% of the UK's population, from 1969 to 2010. The imagery has a high resolution of 5-25cm.

The data were then acquired by the Landmap project. Positioning data were also recorded so that the thermal data could be accurately geolocated in post-processing. The thermal imagery is available as mosaiced img, geotiff or jpeg files for the following areas: Bournemouth, Bradford, Braintree, Coventry, Eastleigh, Gateshead, Gloucester, Gosport, Lewisham, Newcastle, Newcaste-under-lyme, North Tyneside, Poole, Southampton, Southwark, Surrey Heath and Wolverhampton.
