Land Cover Map 2000 (1km percentage aggregate class, GB) Web Map Service

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, data derived from the 25m raster dataset and summarised as dominant values - each pixel provides data on the percentage of a particular land cover within a 1km square at Aggregate class Aggregate Class level (where the 26 Subclasses are combined to form 10 simplified Aggregate Classes).
