BGS Geology - 10k (DiGMapGB-10): Superficial Deposits for UK Urban Areas

Approximately 30% of England, Scotland, and Wales is covered by this 1:10,000 scale geological map. The British Geological Survey (BGS) data identifies landscape areas as polygons attributed with geological names and rock types for the youngest Quaternary deposits. BGS intends to expand coverage to include all large priority urban areas and transport corridors.

Use Cases

• Modeling subsurface conditions for construction based on superficial deposit types like 'glacial deposits' or 'river terrace deposits'
• Assessing natural hazard risks (e.g., flooding, landslides) based on the distribution of unconsolidated sediments
• Planning infrastructure corridors by analyzing geological constraints along road and rail routes
• Studying Quaternary environmental change using the mapped distribution of deposits classified by origin

Strengths

• Data is mapped at a detailed 1:10,000 scale
• Deposits are classified using the formal BGS Rock Classification Scheme (volume 4)
• Focus includes large priority urban areas and transport corridors as stated by BGS

Limitations

• Onshore coverage is partial, covering approximately 30% of Great Britain
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
