PPRi MADON AVAL: Restricted Areas for Flood Risk Prevention

A 2021 dataset from the French Bureau de Recherches Géologiques et Minières (BRGM) describing restricted land-use zones under an approved Risk Prevention Plan (PPR). The data represents spatial points for areas where construction is prohibited or subject to requirements due to flood hazards along the Madon Aval river. It is published as an INSPIRE-compliant download service.

Use Cases

• Mapping construction-prohibited 'red zones' based on high hazard levels described in the plan.
• Analyzing prescribed 'blue zones' for development projects subject to specific requirements.
• Modeling land-use restrictions for areas not directly exposed to risks but still under prohibitions.

Strengths

• Data is structured according to the formal Risk Prevention Plan (PPR) framework, a key government instrument.
• Distinguishes between three regulatory area types ('red', 'blue', and other restricted zones) as described in RPP regulations.
• Published via an INSPIRE download service, suggesting adherence to European spatial data interoperability standards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-05-07 00:00:00; freshness should be verified.
• Row count and spatial extent are unknown, which may limit suitability assessment.
