DDT 48: Jonte River Flood Risk Prevention Plan (PPRN)

French geospatial data for the Jonte River flood risk prevention plan (PPR), adhering to the national COVADIS standard. The dataset, managed by the Bureau de Recherches Géologiques et Minières, was last updated in May 2019. It contains regulatory zoning, hazard intensity maps, and identified issues for areas exposed to flood risk.

Use Cases

• Delineate regulated zones for construction permits based on the regulatory mapping.
• Model flood hazard exposure using the hazard intensity levels documented in the plan.
• Identify and map vulnerable assets and infrastructure based on the documented issues.
• Standardize storage and exchange of PPR data across government ministries using the COVADIS format.

Strengths

• Based on a standardized national data model (COVADIS) for consistency across plans.
• Contains three defined categories of information: regulatory zoning, hazard maps, and identified issues.
• Explicitly covers eight main natural hazards and four technological risks as defined by French law.

Limitations

• Last updated 2019-05-06 00:00:00; freshness should be verified.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
