Description

VERSION 3: The geographical distribution of wetlands in tropical and subtropical areas, excluding small islands, has been mapped with a spatial resolution of 231 meters. The mapping was accomplished by combining a hydrological model with an annual time series of satellite-derived estimations of soil moisture. This integrated methodology encompasses the dynamics of water movement and the extent of surface wetness, which are then combined with geomorphological data to offer an extensive representation of wetland ecosystems.The new version of the Global Tropical and Subtropical Wetlands Map was improved by generalization analysis such as Majority filter and Boundary Clean tools. The generalization analysis tools are used to clean up small erroneous data (eliminate isolated pixels) in the raster. The edges are smoothed by expanding and shrinking boundaries or by growing or shrinking zones based on the values within the neighborhood pixels. Moreover, an ArcGIS layer file was generated for facilitating the visualization. Contact: Dr. Arimatéa C. Ximenes / Email: a.ximenes@cifor-icraf.org
