Land cover map shows habitat distribution in UK

UK: The Centre for Ecology & Hydrology (CEH) on behalf of the long running Countryside Survey partnership launched the UK’s new Land Cover Map (LCM). It is the third in a series by CEH. Previous Land Cover Maps were produced in 1990 and 2000. 
The new map provides a continuous coverage of habitat distributions across the countryside at a 25m resolution. The map was developed using a combination of satellite images and national scale digital mapping data. It is based on 70 satellite images collected between 2005 and 2008 and shows the distribution of different habitats around the UK to a resolution of just 25 metres.
The new map shows the UK land cover as comprising mainly ‘Arable and Horticulture’ and ‘Improved Grassland’ habitats (25 percent each), with the other main land covers being ‘Semi-natural Grassland’ (13 percent) and ‘Mountain, Heath and Bog’ (16 percent). ‘Urban areas’, ‘Coniferous Woodland’ and ‘Broadleaved Woodland’ each make up 6% of the UK. ‘Coastal’ and ‘Freshwater’ habitats contribute to the remaining land surface area.
Land Cover Map is available in a range of data formats and spatial resolutions to suit different user requirements. The most detailed data is supplied as a vector product with a Minimum Mappable Unit of 0.5ha. Each polygon represents a parcel of land and has attributes describing land cover and metadata detailing how this information was derived. Five raster products simplify the information with a 25x25m product giving the most likely Broad Habitat for each polygon. In addition four freely available products summarise the 25x25m raster at the 1x1km level.
