Spatial Metadata: Rivers of Africa

Dataset identification
Title: Rivers of Africa
Date: 2002-04-04
Data content of the dataset
Theme: Hydrology: Rivers
Abstract:The rivers of Africa are derived from the World Wildlife Fund's (WWF) HydroSHEDS drainage direction layer and a stream network layer. The drainage direction layer was created from NASA's Shuttle Radar Topographic Mission (SRTM) 15-second Digital Elevation Model (DEM). The raster stream network was determined by using the HydroSHEDS flow accumulation grid, with a threshold of 1500 upstream cells.
Lineage: The linework of the map was obtained by converting the stream network to a feature dataset with the Hydrology toolset in ESRI ArcGIS. The Flow Direction and Stream Order grids were derived from hydrologically corrected elevation data with a resolution of 15 arc-seconds. The elevation dataset was part of a mapping product, HydroSHEDS, developed by the Conservation Science Program of World Wildlife Fund. Original input data had been obtained during NASA's Shuttle Radar Topography Mission (SRTM).
