Regulatory zoning data for the Natural Flood Risk Prevention Plan (PPRi) of the Le Nohain River in the Nièvre department (58). The dataset, updated on 2023-12-07, is provided by the Bureau de Recherches Géologiques et Minières (BRGM) via an INSPIRE download service. It classifies land into zones based on hazard levels, from prohibited construction areas to zones with specific building requirements.
Use Cases
- Assess land development suitability based on flood hazard zoning categories.
- Model flood risk exposure for insurance or emergency planning using regulatory zone boundaries.
- Verify construction permit compliance against the 'red zone' (no-building) and 'blue zone' (prescribed area) regulations.
- Analyze spatial distribution of flood risk levels mentioned in the Environmental Code (L562-1).
Strengths
- Data is structured according to the formal French Environmental Code (L562-1) categories for natural PPRs.
- Last update timestamp (2023-12 07) is explicitly provided.
- Provided via a standardized INSPIRE download service, suggesting interoperability.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single river catchment (Le Nohain) and department (Nièvre).
