This dataset provides access, via OGC web services (WMS/WFS) compliant with the INSPIRE directive, to the British Geological Survey's hydrogeological mapping theme within the GeoIndex system. It classifies aquifer potential across Great Britain using a threefold division of geological formations: those dominated by intergranular flow in the saturated zone, those controlled by fissures or discontinuities, and less permeable formations. Published by the British Geological Survey, the data supports assessment of groundwater resources and aquifer characteristics at a national scale, and is intended for integration into GIS applications through standard web mapping and feature service interfaces.The hydrogeological map indicates aquifer potential in generalised terms using a threefold division of geological formations: those in which intergranular flow in the saturated zone is dominant, those in which flow is controlled by fissures or discontinuities and less permeable formations includi...
