European River Catchments

The European River Catchments (ERC) data set provides a homogeneous data set at scale 1:1 million that can be used together with the digital topographic data of EuroGlobalMap. It was created using as main input the CCM River and Catchment Database (source: JRC, 2006) version 2.0, extracting watersheds order 5 (CCM2 wso5). The coastline of the European River Catchments was extracted from the EuroGlobalMap water lines data set version 1.1 (source: Eurogeographics). Manual editing, based on different national and international information sources, was needed to obtain data consistency with EuroGlobalMap.

欧洲河流流域（European River Catchments, ERC）数据集提供了比例尺1:100万的均质标准化数据集，可与欧洲全球地图（EuroGlobalMap）的数字地形数据配套使用。该数据集以来源为JRC（2006年）的CCM河流与流域数据库（CCM River and Catchment Database）2.0版为核心输入源，提取其中的5级流域（CCM2 wso5）构建而成。欧洲河流流域的海岸线数据提取自版本1.1的欧洲全球地图水系线数据集（EuroGlobalMap water lines data set version 1.1，来源：Eurogeographics）。为确保数据集与欧洲全球地图（EuroGlobalMap）的数据一致性，需基于多国及国际各类信息源开展人工编辑工作。
