A database of building heights for the main conurbations of the UK, acquired by the Landmap project from The GeoInformation Group's Cities Revealed project. The height information is derived principally from the Cities Revealed LiDAR or Modern aerial imagery (see linked datasets). Each building block has three values: base of building above sea level, top of the building above sea level and height of building above local ground level. Accurate to +/- 0.5m with 95% confidence limits.
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. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

Data collected and prepared by the Landmap team before a copy of the data was obtained by NEODC directly from Landmap.
Data are available as shapefiles, which comprise of .shp, .shx and .dbf files. shp - shape format; the feature geometry itself shx - shape index format; a positional index of the feature geometry to allow seeking forwards and backwards quickly dbf - attribute format; columnar attributes for each shape, in dBase IV format Also provided are prj, sbn, sbx and xml files. prj - projection format; the coordinate system and projection information, a plain text file describing the projection sbn and sbx - a spatial index of the features xml - location and other associated information Free software can be used to open shapefiles, such as Quantum GIS (QGIS) or User-friendly Desktop Internet GIS (uDig) - see links on this record.
