Data Short Description: 
BGS Groundwater Productivity Maps
Data Extended Description: 
The quantitative maps of groundwater productivity, storage, and depth to groundwater can be downloaded below. Each map is available for download as a 5 km resolution grid (xyz ASCII file), and also as a high resolution PDF file. The quantitative maps are the first produced for Africa and are underpinned by dedicated case studies and systematic data/literature reviews. They are designed to show information at the continental, or regional scale (nominally at 1:20M). Detailed description of the methodology, and a full list of data sources, used to develop the groundwater storage and productivity maps can be found in the peer-reviewed paper (Quantitative maps of groundwater resources in Africa) on the maps and supplementary material, published in Environmental Research Letters.View a full description of the methodology used to develop the depth of groundwater map can be found in the BGS Open Report, An initial estimate of depth to groundwater across Africa.
