PPRN Regulatory Zoning: Natural Hazard Risk Perimeters for Savoie Mountain Region

A 2019 dataset from the French Geological Survey (BRGM) containing official regulatory perimeters for natural hazard risk prevention plans (PPRN) in the Savoie mountain region. It includes the prescribed, study, and approved risk exposure zones established by official acts. The data likely contains vector boundaries representing the different stages of PPRN development.

Use Cases

• Mapping regulated land-use zones based on approved risk exposure perimeters.
• Tracking the evolution of hazard study areas based on prescribed and study perimeters.
• Analyzing the spatial impact of official regulatory acts on land development.

Strengths

• Produced by the French Geological Survey (BRGM), an authoritative national institution.
• Distinguishes between three legally significant perimeter types (prescribed, study, approved).
• Last updated timestamp (2019-11-13) is explicitly provided.

Limitations

• Row count, file formats, and column-level documentation are unknown.
• Last updated 2019-11-13; freshness should be verified for current applications.
• Data may reflect geographic bias inherent to the Savoie mountain region.
