Land cover map 2007 (LCM2007) is an object-based land cover map for the UK containing around 10 million objects. The LCM2007 spatial framework is based on the generalisation of national cartography products (OS MasterMap for Great Britain and Ordnance Survey Northern Ireland for NI). 34 composite images (based on summer and winter data) were classified using a maximum likelihood classifier. Areas where composite data were not available were filled with classifications from single-date data. A set of knowledge-based enhancements (KBEs) were then applied to refine the classification using ancillary data sets, including soil and altitude data. The final product showed a correspondence of 83%, when compared to 9127 ground reference polygons. A range of LCM2007 data products are available ranging from the full vector data set, with 10 attributes per polygon, to a 25m raster data set and a series of 1km raster products.
