The new version of the Global Tropical and Subtropical Wetlands Map was improved by generalization analysis such as Majority filter and Boundary Clean tools. 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 (Gumbricht et al. ![]() The Global Wetlands Map covers the tropics and subtropics regions (40° N to 60° S 180° E to -180° W), excluding small islands.
