The "Major River Basins of the World" is an ongoing GIS project of the Global Runoff Data Centre (GRDC) that aims at the provision of a set of shape files for the use with Geographic Information Systems (GIS). This dataset was created for the generation of GRDC map products and will be updated from time to time whenever extensions are required by future GRDC projects. At present the dataset comprises the GIS layer of 405 river basins and 687 associated rivers.
GRDC data will only be provided for non-commercial uses.
