|Abstract:||Available land use/cover maps differ in their spatial extent and in their thematic, spatial and temporal resolutions. Due to the costs of producing such maps, there is usually a trade-off between spatial extent and resolution. The only European-wide, consistent and multi-temporal land use/cover dataset available is the CORINE Land Cover (CLC) map. Despite the value and usefulness of CLC, its minimum mapping unit of 25 hectares considerably limits its applications at large scales of analysis. Our objective was to improve the spatial detail of CLC 2006 by incorporating land use/cover information present in finer thematic maps available for Europe such as the CLC change map, Soil Sealing Layer, Tele Atlas® Spatial Database, Urban Atlas, and SRTM Water Bodies Data. Relevant data from these datasets were extracted and prepared to be combined with CLC in a stepwise approach. Each step increased the level of modifications to the original CLC. This process generated a newly refined version of the CLC 2006 map with an improved minimum mapping unit of 1 hectare for all types of artificial surfaces and inland waters, while keeping constant the original 100 meter cell size. A validation of the new map was carried out using LUCAS 2006 sample points (European Land Use/Cover Area frame Statistical survey). The observed increase in spatial detail was done, however, at the cost of the cartographic consistency.|
