Land Cover Map 1990

The Land Cover Map of Great Britain 1990 (LCMGB) was the first digital land cover map for Great Britain derived from satellite imagery. LCMGB is a 25m x 25m pixel land cover product describing land cover in 1990. It was produced by automated classification techniques where each pixel is assigned to a land cover class based upon its spectral characteristics.
 Please note: LCMGB covers Great Britain only, Northern Ireland's land cover was not included in this product

LCMGB was produced using supervised maximum likelihood classifications of Landsat Thematic Mapper data (Fuller et al 1994a). The map, based on a 25m grid, records 25 cover types, consisting of sea and inland water, beaches and bare ground, developed and arable land, and 18 types of semi-natural vegetation.

Data availability

25m raster
The 25m raster dataset is based on a grid with a 25m resolution. It categorises each cell of the grid as one of 25 target land cover types. For more information and to get the data visit doi: 10.5285/3d974cbe-743d-41da-a2e1-f28753f13d1e

1km raster
The 1km raster datasets are derived from the 25m raster data, are at a much reduced resolution.  Two 1km products are available:

  • Dominant target class, available at doi: 10.5285/4e3fe599-1ae9-4dbb-9476-bfc74fe90b4e. 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 the higher resolution data.
  • Percentage target class - available at doi: 10.5285/0172cc8c-8b5c-46cf-b08a-785ab832e88c. In this dataset there are 25 layers, one for each target cover-type. Within each layer, each 1km grid cell is assigned a value which represents the integer percentage of that particular target cover-type occurring within that cell.
