Africa Groundwater Atlas Country Hydrogeology Maps

A collection of free GIS-enabled country maps showing aquifer type, relative aquifer productivity and hydrogeologically significant geological units at a nominal scale of 1:5,000,000 for 43 African countries.

Provider British Geological Survey – Africa Groundwater Atlas

Resolution National polygon hydrogeology and geology maps at a nominal scale of 1:5,000,000; approximately 1 centimetre on the map represents 50 kilometres on the ground

JPL GRACE and GRACE-FO Monthly Global Water Storage Anomalies

A monthly global dataset of water-storage anomalies derived from GRACE and GRACE-FO satellite gravity observations and processed by NASA JPL using the Mascon approach. The data can support large-scale groundwa…

Provider NASA Jet Propulsion Laboratory

Resolution Values are sampled on a 0.5-degree latitude-longitude grid, approximately 56 kilometres at the equator. However, the effective native resolution is approximately 3 degrees because the solution is based on 4,551 equal-are

Netherlands Groundwater Monitoring Wells and Level Observations – DINO and BRO

Dutch national groundwater dataset providing monitoring wells, screened intervals, station metadata and groundwater-level time series from the DINO repository and BRO register.

Provider TNO Geological Survey of the Netherlands – DINOloket

Resolution Individual groundwater-monitoring well and monitoring-tube locations; each tube can represent a different screened depth or aquifer interval

SADC Hydrogeological Map and Atlas

Regional hydrogeological map and atlas describing aquifer types, lithology, groundwater-flow characteristics and groundwater potential across the SADC region.

Provider SADC Groundwater Management Institute – Groundwater Information Portal

Resolution Regional map scale of approximately 1:2,500,000; suitable for regional and transboundary assessment but not for local borehole siting or engineering design
