This dataset is developed as part of a GIS-based information system on water resources for the African continent. The attributes table now includes a field named 'Regime' with tentative classification of perennial ('P') and intermittent ('I') streams. The stream network dataset consists of the following information: the origin node of each arc in the network (FROM_NODE), the destination of each arc in the network (TO_NODE), the Strahler stream order of each arc in the network (STRAHLER), numerical code and name of the major basin that the arc falls within (MAJ_BAS and MAJ_NAME) - area of the major basin in square km that the arc falls within (MAJ_AREA) - numerical code and name of the sub-basin that the arc falls within (SUB_BAS and SUB_NAME) - area of the sub-basin in square km that the arc falls within (SUB_AREA) - numerical code of the sub-basin towards which the sub-basin flows that the arc falls within (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea). The raster stream network was determined by using the HydroSHEDS flow accumulation grid, with a threshold of about 1000 km² upstream area. The source of the drainage direction layer was the 15-second Digital Elevation Model (DEM) from NASA's Shuttle Radar Topographic Mission (SRTM). (There may be an additional charge for telephone bookings).The rivers of Africa dataset is derived from the World Wildlife Fund's (WWF) HydroSHEDS drainage direction layer and a stream network layer.
