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 a relevant topographic base at the time of production. Full Great Britain coverage is available. The data is available in vector format. BGS licensing terms and conditions apply to external use of the data.
