Summary

This dataset contains the Flow Accumulation (FA) for Africa from the Hydrologic Derivatives for Modeling and Analysis (HDMA) database. The FA data were developed and distributed by processing units. There are 19 processing units for Africa. The distribution files have the number of the processing unit appended to the end of the zip file name (e.g. af_fa_3_2.zip contains the FA data for unit 3-2). The HDMA database provides comprehensive and consistent global coverage of raster and vector topographically derived layers, including raster layers of digital elevation model (DEM) data, flow direction, flow accumulation, slope, and compound topographic index (CTI); and vector layers of streams and catchment boundaries. The coverage of the [...]
