This dataset comprises three distinct layers delineating the boundaries of sedimentary basins across Africa. In particular
Basins (greater than 2km): Boundaries of sedimentary basins in Africa with sedimentary thicknesses of at least 2 km. Contains geological information about the sedimentary basins such as basin name, class/type and age. Created by extracting data from open sources into a series of shapefiles and rasters containing information on culture, geology, geothermal and geophysical data.
Basins Nyberg & Howell (2015): Boundaries active sedimentary basin/depositional centers of Africa categorised by basin structure and climate-zone.
Basins Robertson (2019): Boundaries of sedimentary basins in Africa. Part of the Robertson new ventures product suite. Includes information on the name, geometry, type and the hydrocarbon exploration status of a given basin.
Basins Evenick (2021): Boundaries of sedimentary basins in Africa compiled from previous work. The sedimentary basins have been revised to simplify the borders of sedimentary basins, as the definition of a basin (boundary) is often contested. Includes the name, geometry, type, age and evaporite content of a given basin.
This dataset provides the hydrological boundaries for major river basins and sub-basins across the African continent. Developed by the FAO Land and Water Division under the AQUASTAT program, the data delineates Africa’s drainage systems based on a hydrologically corrected Digital Elevation Model (DEM) at a 1 km resolution.
Designed for use within GIS-based water resource information systems, this dataset serves as a foundational layer for analyzing African hydrology. It was originally published as part of the FAO Land and Water Digital Media Series #13: "Atlas of Water Resources and Irrigation in Africa."
