Topographic Moisture Potential

The Africa Topographic Moisture Potential layer classifies the landscape of Africa as either upland or lowland (and other depressions) area. It was produced as part of the USGS’s Africa Ecosystems Mapping project to create maps depicting standardized, terrestrial ecosystem models. Substrate moisture regimes strongly influence the differentiation and distribution of terrestrial ecosystems, and therefore topographic moisture potential is one of the key input layers in this biophysical stratification.
