newGeoSure Insurance Product version 7 2016.3

Great Britain is covered by this dataset, which models the potential insurance risk from six natural ground movement hazards at a postcode level. The British Geological Survey produced it by evaluating hazards like landslides and shrink-swell clays using statistical analysis and expert elicitation. The product is updated biannually, uses Ordnance Survey Code-Point® data (version 2016.3), and is designed for use at a 1:50,000 scale with 50-meter ground resolution.

Use Cases

• Identify properties at high risk for insurance purposes based on the six combined GeoSure hazards.
• Estimate regional susceptibility to ground movement for risk modeling based on postcode-level data.
• Support actuarial calculations for property insurance based on geological hazard potential.
• Inform land-use planning and development decisions based on ground stability assessments.

Strengths

• Covers six specific geological hazards: landslides, shrink-swell clays, soluble rocks, running sands, compressible ground, and collapsible deposits.
• Provides national coverage across Great Britain at a 1:50,000 scale with 50-meter resolution.
• Updated biannually with new releases of Ordnance Survey Code-Point® 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.
• The dataset has been superseded, as noted in the description.
