If a facility happens to fall on or close to a boundary of the quads, you may also want the DEM files of its surrounding quads, since the plume may go that way(s). This dataset contains the Digital Elevation Model (DEM) for Africa from the Hydrologic Derivatives for Modeling and Analysis (HDMA) database. The DEM 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_dem_3_bltadwin.ru contains the DEM data.
