The Land Cover Map of Great Britain (1990) is a digital dataset, providing a classification of land cover types into a maximum of 25 classes, available at 25m and 1km resolutions. The map was produced using supervised maximum likelihood classifications of Landsat 5 Thematic Mapper satellite data. The map includes classes such as 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. It was produced by the Institute of Terrestrial Ecology in the early 1990s.
