Regulatory flood zones established by approved PPRIs (Plans de Prévention des Risques) in Dawn. The dataset includes all areas defined by the Prefectural Decree approving the PPRI, including white areas not subject to regulatory constraints. The data was provided by the Bureau de Recherches Géologiques et Minières and last updated on 2019-03-28.
Use Cases
- Mapping flood hazard zones for land-use planning based on the regulatory zoning.
- Informing populations about flood risk areas as described in the PPR dossier.
- Reducing vulnerability by defining measures based on the established regulatory constraints.
- Studying the spatial distribution of 'white areas' included in the study but not subject to constraints.
Strengths
- Dataset is based on official Prefectural Decrees approving PPRIs.
- Includes 'white areas' (areas in the study zone without constraints), providing a complete study boundary.
- Last update timestamp (2019-03-28) is explicitly provided.
