LCM2000 is a parcel-based thematic classification of satellite image data covering the entire United Kingdom. The map updates and substantially upgrades the Land Cover Map of Great Britain (LCMGB) 1990. Like the earlier LCMGB, LCM2000 is derived from a computer classification of satellite scenes obtained mainly from the Landsat sensor, but in addition to LCMGB, it also covers Northern Ireland, producing for the first time an all-UK dataset. It also incorporates information derived from other ancillary datasets. LCM2000 was classified using a hierarchical nomenclature corresponding to the Joint Nature Conservation Committee (JNCC) Broad Habitats, which encompasses the entire range of UK habitats. In addition, it recorded further detail where possible and incorporating land cover classes sought by other users. LCM2000 is produced in both vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions. Data consists of a 1km grid, derived from the 25m raster dataset. Each pixel provides the percentage of a particular land cover within a 1km square at Subclass level. The Land Cover Map of Great Britain (1990) is a digital dataset, providing classification of land cover types into 25 classes, at a 25m (or greater) resolution. The map was produced using supervised maximum likelihood classifications of Landsat 5 Thematic Mapper data. The map, based on a 25m grid, comprises 25 classes, including sea and inland waters, bare, suburban and urban areas, arable farmland, pastures and meadows, rough grass, grass heaths and moors, bracken, dwarf shrub heaths and moorland, scrub, deciduous and evergreen woodland, and upland and lowland bogs. It can be used to plan, manage or monitor agriculture, ecology, conservation, forestry, environmental assessment, water supplies, urban spread, transport, telecommunications, recreation and mineral extraction. Dataset consists of 1km class percentage values, derived from the 25m raster dataset. Note that the Band numberings in the dataset run from 1-27 rather than 0-26 and therefore each band relates to the one below it in the subclass code list (i.e. 1 = Unclassified, labelled as 0 in the list).
