BGS Geology - 10k (DiGMapGB-10): Mass Movement Polygons for the UK

Onshore coverage of Great Britain includes landscape areas attributed with types of mass movement, such as landslips and foundered strata, at a 1:10,000 scale. The data is provided by the British Geological Survey (BGS) in vector polygon format, but coverage is partial, with approximately 30% of England, Scotland, and Wales available in this version 2 release. BGS intends to expand coverage, focusing on large priority urban areas and transport corridors.

Use Cases

• Identify landslide hazard zones based on mapped mass movement polygons.
• Assess ground stability for infrastructure projects based on the classification of landslip types.
• Model geological risk in urban areas based on the inclusion of foundered strata (subsidence collapse) data.
• Support land-use planning decisions based on the spatial distribution of mass movement deposits.

Strengths

• Data is provided at a detailed 1:10,000 scale.
• Includes both mass movement deposits and foundered strata not described in the standard rock classification.
• Produced by the authoritative British Geological Survey (BGS).

Limitations

• Coverage is partial, with only about 30% of onshore Great Britain included.
• Historical recording of mass movement events by BGS has not been complete, and dynamic changes may have occurred since release.
• Column-level documentation is absent; field semantics must be inferred after download.
