Primary humid tropical forests provide numerous global ecosystem services, but are under continuing threat of clearing from economic drivers. To facilitate national land use planning and balancing the goals of economic development and maintenance of ecosystem services, a set of primary humid tropical forest forests maps were created by the UMD GLAD team. The primary forest extent was mapped for the year 2001 at a spatial resolution of 30 meters using globally acquired, free-of-charge, and consistently processed Landsat imagery.
Here, were presenting the national year 2001 primary humid tropical forests maps for Brazil, Indonesia, and the Democratic Republic of the Congo (DRC). Country boundary were obtained from the http://www.gadm.org/. All maps are in geographic coordinates (WGS84 reference system) with pixel size of 0.00025 degree. The pixel value are: 0 – outside country; 1 – other land; 2 – primary humid tropical forests 2001.
