PPRN: Natural Hazard Prevention Plan for Gajan, France

Gajan municipality's Plan for the Prevention of Natural Hazards (PPRN) is a geospatial dataset following the COVADIS standard. It was produced by the Bureau de Recherches Géologiques et Minières and last updated in February 2024. The plan includes regulatory zoning maps, hazard intensity levels, and identified issues for risks like floods, earthquakes, and forest fires.

Use Cases

• Delineate regulated zones for construction based on regulatory mapping.
• Model exposure to specific hazards like floods or forest fires based on hazard documents.
• Assess land-use conflicts by overlaying hazard intensity maps with infrastructure layers.
• Support environmental impact studies by referencing the standardized geographical data on risks.

Strengths

• Adheres to the national COVADIS data standard for risk prevention plans, ensuring interoperability.
• Covers eight main natural hazards, including floods, earthquakes, and forest fires, as defined by French law.
• Includes three standardized categories of information: regulatory zoning, hazard mapping, and identified issues.

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.
