资源简介：
The coverage is a South African surface drainage network for GIS, originally based on a 1994 1:500 000 rivers coverage from the Chief Directorate of National Geo-spatial Information. This version is made available `as is` for the convenience of those who need a medium-scale river coverage for display or modelling: the developers would welcome any comments relating to errors or areas for improvement.
