The Catchment Characterisation Model (CCM2) database covers the entire European continent, including the Atlantic islands, Iceland and Turkey. It includes a hierarchical set of river segments and catchments based on the Strahler order, a lake layer and structured hydrological feature codes based on the Pfafstetter system. It allows for analysis from the regional to the continental scale, corresponding to traditional mapping scales of up to 1:500,000. CCM2 covers an area of about 12,000,000 square kilometers and includes more than 2,000,000 primary catchments. These can be aggregated to drainage basins at different hierarchical levels, forming, for example, about 650 river basins of more than 1000 square kilometers. CCM2 further includes a coastline, fully congruent with the river basins, and some 70,000 lakes. The layers are generated from a 100 meters resolution digital terrestrial elevation model. The following layers are available: Seaoutlets: the major river basins, Main drains: the major rivers, Lakes: all surface water larger than 25x25 metres, Coastlines: coast line extracted from Image2000 imagery, River segments: Drainage channels from the primary catchments, Catchments: Primary catchments. This data-set refers to Lakes and River basins.
