WISE EIONET spatial data sets

The European environment information and observation network (Eionet) spatial data sets include information about European river basin districts, river basin district sub-units, surface water bodies, groundwater bodies and monitoring sites. The data sets are part of the Water Information System for Europe (WISE), and compile information reported to the European Environment Agency (EEA) since 2001. For the EEA Member countries and cooperating countries not reporting under WFD, the EIONET spatial data sets are the most up-to-date information available in WISE. The coverage is complete for Switzerland, Serbia and Kosovo and partial for the remaining countries (Liechtenstein, Turkey, Albania, Bosnia and Herzegovina, Montenegro, North Macedonia). For the 27 European Union Member States, Iceland, Norway and the United Kingdom, the Water Framework Directive (WFD) reference spatial data sets are the most complete and up-to-date information available in WISE (only the EIONET monitoring sites and EIONET water bodies that could not be mapped to WFD spatial objects are included in the EIONET spatial data set).
