Wetlands play a fundamental role in climate change mitigation, and provide essential ecosystem services. Yet there is still a lot we don’t know about their precise distribution, extent and inter-annual variability around the world, particularly in the tropics.
The Global Wetlands Map is an initiative to collect and share information on tropical wetlands in a visual format. Users can access data and contribute their own, using standard geographic information systems software such as ArcGIS.[...Distribution of wetland that covers the tropics and sub tropics, excluding small islands. It was mapped in 231 meters spatial resolution by combining a hydrological model and annual time series of satellite-derived estimates of soil moisture to represent water flow and surface wetness that are then combined with geomorphological data.]
