BGS GeoSure

The BGS GeoSure datasets identify areas of potential hazard and, therefore, potential natural ground movement, in Great Britain. These data have been produced by BGS geologists and geotechnical specialists and are presented as six GIS data layers relating to the cause of the geohazard.

BGS Geology dataset BGS GeoSure dataset
1:50 000 high-resolution dataset, providing information about six natural ground subsidence hazards in Great Britain.
BGS GeoSure Shrink Swell 3D London BGS GeoSure shrink–swell 3D London
