The Compressible Ground dataset from the British Geological Survey (BGS) provides a generalized, user-friendly view of ground movement susceptibility across Great Britain. It rates areas on a hexagonal grid with a 5km side length as Low, Moderate, or Significant based on the highest susceptibility identified within each cell. The dataset, version 8, was last updated on 2026-04-09.
Use Cases
- Regional hazard screening for construction projects based on compressible ground susceptibility ratings.
- Informing planning decisions and identifying subsidence causes based on the referenced GeoSure reports.
- Modeling geological risk for infrastructure development based on the hexagonal grid generalization.
- Assessing the potential for ground compression under load based on the classification of superficial deposits like peat or alluvium.
Strengths
- Provides complete national coverage for Great Britain.
- Offers a user-friendly, generalized format on a standardized 5km hexagonal grid.
- Ratings (Low, Moderate, Significant) are based on the BGS Digital Map and expert knowledge.
Limitations
- The spatial summarization process may lead to under or overestimation of the actual hazard extent.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file format details are unknown, which may limit suitability assessment.
