The maps have two hydrogeological themes: -geology with geological categories that reflect significant hydrogeological units; and -hydrogeology, combining classifications of aquifer type and productivity. The maps were produced as part of the Africa Groundwater Atlas project.

The 1:5 million scale geology map was originally published by UNESCO (Furon and Lombard 1964), and was digitised by, and is made available through, the USGS (Persits et al. 2002). This map was used by the British Geological Survey to develop three Africa-wide quantitative groundwater maps, released in 2012. The Atlas country hydrogeology maps are a further development of these Africa-wide groundwater maps, incorporating additional geological and hydrogeological information from individual countries. Where possible, the country hydrogeology maps have been validated in collaboration with hydrogeologists from the relevant countries who are co-authors on the relevant country pages of the Africa Groundwater Atlas.
