The information on this website is based on the British Geological Survey's National Geological Model, a low-resolution, 3D model of the geology of the UK. The information is presented at a national scale and is intended to provide basic information about the distribution of the rock formations and their spatial relationships at the national scale. Information describing the methods that were used to generate the maps and how to use the data is also available. Note that the maps should not be used as the basis for regional- or site-scale assessments or investigations.
The maps and data were created between August 2011 and August 2013 and may be updated in the future when more detailed national scale surface mapping becomes available. The maps were produced as part of a larger project, the iHydrogeology project, co-funded by the Environment Agency (EA) and BGS. Consequently, they only cover England and Wales. It is hoped that the maps will be updated and extended to cover Scotland and Northern Ireland in the future.
The data and maps have been produced as part of a project, called iHydrogeology, which was jointly funded by the British Geological Survey and the Environment Agency.
The three aims of the iHydrogeology project have been to:
