A 2026-updated national dataset from the British Geological Survey assessing the potential for ground dissolution and karst-related hazards across Great Britain. It identifies four main soluble rock types—limestone, chalk, gypsum, and salt—and models associated risks like sinkhole formation and subsidence. The methodology is based on the BGS Geology digital map and expert knowledge of geological formations.
Use Cases
- Risk assessment for building and infrastructure projects based on identified soluble rock types.
- Informing land-use planning decisions based on potential subsidence and sinkhole formation.
- Modeling geological hazards based on expert-defined formation behavior and karst character.
Strengths
- Provides complete national coverage for Great Britain.
- Based on authoritative BGS Geology digital map and expert knowledge.
- Data is available in multiple GIS formats, including ESRI Shapefiles and MapInfo.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is in the future (2026-04-09).
