Map

The Global Wetlands Map covers the tropics and subtropics regions (40° N to 60° S; 180° E to -180° W), excluding small islands. This mapping is a hydro-geomorphological model based on an Expert System approach to estimate wetland areas, which relies on three biophysical indices related to wetland and peat formation: (1) long-term water supply exceeding atmospheric water demand; (2) annually or seasonally waterlogged soils; and (3) a geomorphological position where water is supplied and retained. 

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.
