Global Land Use Data Sets
Information on soils, vegetation types, cultivated areas, wetlands and inundated areal fraction at 1- x 1-degree resolution for the Earth are available. Global FAO soil units data distinguish 27 soil types. The vegetation data set gives the global distribution of 32 vegetation types based on the UNESCO classification system. The cultivation data set describes the global distribution of cultivation intensity, distinguishing 5 classes. The wetlands data set gives the global distribution of wetlands, distinguishing 5 classes. These 5 wetlands classes were collapsed from 12 original classes that defined worldwide wetland ecosystems on the basis of environmental characteristics governing methane emissions. The inundated areal fraction data set is the global distribution of inundated areal fraction of 1-degree cells. These data can be combined with the wetlands data to calculate global wetland area.
