BGS Geology - 10k (DiGMapGB-10) Bedrock Version 2: Geological Map of Great Britain

Great Britain's bedrock geology is mapped at a 1:10,000 scale, covering approximately 30% of England, Scotland, and Wales. The British Geological Survey (BGS) data identifies landscape areas as polygons attributed with geological names, rock types, and ages spanning from the Archean eon to the Pliocene. It is available in vector format under a BGS data licence.

Use Cases

• Map subsurface geology for urban development based on the 1:10,000 scale data covering priority urban areas.
• Classify rock types for engineering projects based on the BGS Rock Classification Scheme attribution.
• Analyze geological time periods for academic research based on the age attribution from the Archean to the Pliocene.
• Plan infrastructure corridors based on the data's focus on road and rail transport routes.

Strengths

• Data is at a detailed 1:10,000 scale.
• Covers approximately 30% of onshore Great Britain.
• Includes rock classification based on the formal BGS Rock Classification Scheme.
• Attributes geological ages spanning from 7500 million years ago to 58 million years ago.

Limitations

• Onshore coverage is partial at 30%; many areas are not included.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
