The dataset consists of a 1km grid with a full set of the 25 target classes (or 'sub' classes). Each 1km contains the dominant habitat class, derived from a higher resolution (25m) dataset. The map was produced using supervised maximum likelihood classifications of Landsat 5 Thematic Mapper satellite data. The 25 mapped classes include 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 potentially be used to plan, manage or monitor agriculture, ecology, conservation, forestry, environmental assessment, water supplies, urban spread, transport, telecommunications, recreation and mineral extraction. The map was produced in the early 1990s by a forerunner of the Centre for Ecology & Hydrology, the Institute of Terrestrial Ecology, at Monks Wood.","distributionFormats":[{"name":"ESRI ASCII grid","version":"unknown"},{"name":"Esri .hdr RAW raster","version":"unknown"},{"name":"TIFF","type":"image/tiff","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"id":"4e3fe599-1ae9-4dbb-9476-bfc74fe90b4e","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/4e3fe599-1ae9-4dbb-9476-bfc74fe90b4e.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Land Cover","uri":"http://inspire.ec.europa.eu/theme/lc"}],"keywordsOther":[{"value":"land cover","uri":"http://www.eionet.europa.eu/gemet/concept/4612"},{"value":"habitat","uri":"http://www.eionet.europa.eu/gemet/concept/3808"}],"keywordsPlace":[{"value":"Great Britain"},{"value":"England","uri":"http://sws.geonames.org/6269131"},{"value":"Scotland","uri":"http://sws.geonames.org/2638360"},{"value":"Wales","uri":"http://sws.geonames.org/2634895"}],"keywordsTheme":[{"value":"Land cover","uri":"http://onto.nerc.ac.uk/CEHMD/topic/11"}],"lineage":"The Land Cover Map of Great Britain (LCMGB) was produced (at the Institute of Terrestrial Ecology (ITE) Monks Wood) using supervised maximum likelihood classifications of Landsat Thematic Mapper satellite data See online supporting information for further details.","metadataDate":"2026-06-29T15:51:23","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/4e3fe599-1ae9-4dbb-9476-bfc74fe90b4e.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Morton","givenName":"Dan","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Lancaster Environment Centre, Library Avenue, Bailrigg","city":"Lancaster","administrativeArea":"Lancashire","postalCode":"LA1 4AP","country":"United Kingdom"},"fullName":"Morton, D.","pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"1993-01-01T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"reasonChanged":"The original 1990 Land Cover Map data set had a different spatial structure and set of land cover classes to the Land Cover Maps from 2015 onwards.
