BGS 1:50,000 + Geosure A1 Portrait
This product includes the most recent interpretation of the geology of Great Britain as mapped to 1:50,000 scale by the British Geological Survey. This is overlain on 1:50,000 mapping from the Ordnance Survey.
Although the geology of Great Britain remains largely unchanged over the geologically insignificant timescale of the human lifetime, there are constant updates to the mapping as the understanding of the often hidden 'surface' geology is improved by growing knowledge, technological advances in investigation and new exposure through excavation and natural ground movement.
The data is available for the majority of Great Britain apart from a few small sheets in Wales (please refer to our attached coverage map) which are currently being produced.
This British Geological Survey 1:50,000 scale Geology product offers:
OS 1:50,000 mapping
BGS Bedrock (Solid) Geology
BGS Superficial (Drift) Geology
