The European Environmental Agency (EEA) provides the CORINE ( COoRdinate INformation on the Environment ) land data base, a pan-European land cover/ land use map for non-commercial use. The Minimum Mapping Unit (MMU) is set to 25 hectares. Various documentation and reports (methodology, nomenclature, etc.) are available at EEA's CORINE Land Cover Publications webpage.

CORINE2000
CORINE2000 (or CLC2000) is the year 2000 update of the first CORINE database that was finalised in the early 90s. Normally a registration is required to obtain tiles of the seamless vector database in the form of ESRI shapefiles from EEA’s download web-service. The raster equivalent version of the CORINE2000 map derived from the seamless vector database is of 100m pixel resolution [see Raster data section below]. Nevertheless, there is the possibility to get specific tiles using the wget tool under linux.
Update 2017: CORINE is now available from here: http://land.copernicus.eu/pan-european/corine-land-cover
