The European Wetland Map ('EWM')

The European Wetland Map (EWM) improves the current state of knowledge on wetlands across Europe by locating, assessing and merging the latest geospatial data, e.g., on the distribution and types of floodplains and wetlands – coastal, mineral and peatlands in a bottom-up approach. It brings together existing data into a comprehensive, easily accessible resource to make wide spread European wetlands visible and enhance their analysis, understanding and management. The approach is described in the attached report.

The EWM is made up of individual datasets for each of the countries included. A polygon and a raster dataset on the geographical distribution of the wetlands considered  is available on country basis in an ArcGIS geodatabase and as a country-specific Geo-TIFF collection (grid size: 1 arcsecond).

This work is part of the research and innovation projects “ALFAwetlands- Wetland restoration for the future” Grant Agreement No. 101056844 and “WET HORIZONS” Grant Agreement No. 101056848, funded by the Horizon Europe Framework Program of the European Union. Moreover, this work is part of the project "Building the European Peatland Initiative: a strong alliance for peatland climate protection in Europe", Grant Agreement No. 81290291. This project is part of the European Climate Initiative (EUKI) of the German Federal Ministry for Economic Affairs and Climate Action (BMWK).
