Major rivers in Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Sudan and Uganda.

The FGGD inland water bodies map is a global raster datalayer with a resolution of 5 arc-minutes. It contains the value -997 where inland water bodies is present, the value 1 for the land. The information of inland water bodies is from the 1991 version of Digital Soil Map of the World.

The rivers have been produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the year 1999.

GNS_RIV: GNS/GeoNet named river confluence & outflow locations Value-added derivative of source w/non-diacritical names of river confluence's. The GNS_RIV shapefile data layer is comprised of 138700 derivative point gazetteer features derived based on 1:250 000 data originally from GEOnet. The layer provides nominal analytical/mapping at 1:250 000. Data processing is complete globally, this is an African subset. Acronyms and Abbreviations: GNS/GeoNet - NIMA?s Geographic Names Server Gazetteer of Named Locations; NIMA - U.S. National Imagery & Mapping Agency, formerly the U.S. Defense Mapping Agency (DMA).

The full resolution dataset of rivers have been produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the year 1999.

The full resolution dataset of rivers have been taken from the DCW dataset.

The full resolution dataset of rivers have been produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the period 1994-1999.

The rivers of Central America dataset is derived from the World Wildlife Fund's (WWF) HydroSHEDS drainage direction layer and a stream network layer. The source of the drainage direction layer was the 15-second Digital Elevation Model (DEM) from NASA's Shuttle Radar Topographic Mission (SRTM). The raster stream network was determined by using the HydroSHEDS flow accumulation grid, with a threshold of about 1000 km² upstream area. 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 attributes table now includes a field named "Regime" with tentative classification of perennial ("P") and intermittent ("I") streams.

The full resolution dataset of rivers was produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the year 1995.
