Digital Geological Map Data of Great Britain - 50k (DiGMapGB-50) SURFACE Version 6.19
The data overlays superficial polygons on bedrock polygons giving a representation of the geology at the surface. Sourced from 1:50000 DiGMapGB-50 Version 6 where available, augmented by additional data from the following sources in the order - new 1:25000 mapping, new 1:35000 Superficial Derived Products interpretation, 1:250000 DiGMapGB-250 Bedrock or 1:625000 DiGMapGB-625 V4 Superficial. The attributes therefore include both superficial and bedrock plus their source. The geology is fitted to
