Risk Zone of a PPRN (Risle PPRI) in Orne: Natural Hazard Areas

Hazard zones for the Risle PPRI in the Orne department of France, representing areas exposed to one or more natural hazards. The dataset was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated on August 4, 2020. It is a compiled synthesis of hazard data used for regulatory risk prevention planning.

Use Cases

• Mapping flood or natural hazard exposure for property assessment based on the described hazard zones.
• Analyzing land-use restrictions and development prescriptions based on the regulatory zoning framework mentioned.
• Modeling the impact of protective structures on hazard classification, as areas behind them are still considered at risk.
• Integrating hazard data with other geospatial layers for multi-risk analysis, as the description mentions multi-hazard PPRNs.

Strengths

• Data is produced by a recognized geological and mining research organization (Bureau de Recherches Géologiques et Minières).
• Hazard zoning is graduated according to level of hazard, suggesting a detailed risk assessment methodology.
• Includes areas protected by structures, providing a conservative risk assessment as described.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2020-08-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
