HydroBASINS data provides a series of polygon layers that depict watershed boundaries and sub-basin delineations at a global scale. The goal of this product is to provide a seamless global coverage of consistently sized and hierarchically nested sub-basins at different scales (from tens to millions of square kilometers), supported by a coding scheme that allows for analysis of watershed topology such as up- and downstream connectivity. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>All HydroBASINS layers were derived from World Wildlife Fund’s HydroSHEDS data based on a grid resolution of 15 arc-seconds (approximately 500 m at the equator). Watersheds were delineated in a consistent manner at different scales, and a hierarchical sub-basin breakdown was created following the topological concept of the Pfafstetter coding system. The resulting polygon layers are termed HydroBASINS and represent a subset of the HydroSHEDS database. This shapefile contains (sub-)basin polygons for Africa at Pfafstetter level 6.</SPAN></P></DIV></DIV></DIV> |
