Digital Geological Map Data of Great Britain - 50k (DiGMapGB-50) WMS Version 6.20

The data is a simplified version of DiGMap for use on the web and for smart applications such as iGeology. Sourced from 1:50000 DiGMapGB-50 Version 6 where available.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. Near 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.
