LCMGB (1990) is a raster product available in different resolutions. A 25x25m raster gives the most likely land cover class for each pixel. Four freely available 1x1km raster products summarise the 25x25m raster. Metadata for the LCMGB raster formats are available in Table 2 and Table 3.

Raster data format

Scale: 25m and 1km pixel size
