newGeoSure Insurance Product: Natural Ground Movement Risk for Great Britain

Great Britain is covered by this dataset, which models potential insurance risk from six natural ground movement hazards: landslides, shrink-swell clays, soluble rocks, running sands, compressible ground, and collapsible deposits. The British Geological Survey produced it by evaluating hazards using statistical analyses and expert elicitation, then linking results to a postcode database updated biannually. The product is designed for use at a 1:50,000 scale, providing 50-meter ground resolution.

Use Cases

• Identify properties at risk from landslides based on the integrated hazard evaluation.
• Estimate insurance premiums for low-rise buildings based on shrink-swell clay susceptibility.
• Map regional exposure to soluble rock hazards using the postcode-linked geospatial data.
• Assess foundation risk from running sands or compressible ground for property portfolios.

Strengths

• Covers six distinct natural ground movement hazards for national coverage across Great Britain.
• Provides 50-meter ground resolution, designed for use at a 1:50,000 scale.
• Linked to a postcode database that is updated biannually with new Ordnance Survey data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
