Hazard areas defined by the Natural Risk Prevention Plan (PPRN) for the Meu, Garun, and Vaunoise basin in Ille-et-Vilaine, France. The dataset, produced by the Bureau de Recherches Géologiques et Minières (BRGM), represents zones exposed to one or more natural hazards, with hazard levels based on the probability and intensity of dangerous phenomena. It was last updated on April 26, 2019.
Use Cases
- Land-use planning and zoning based on mapped hazard intensity levels.
- Risk assessment for property development using the hazard probability and intensity data.
- Modeling the impact of protective structures on hazard exposure, as areas behind them are still considered at risk.
- Identifying zones of zero or insignificant hazard for regulatory classification.
Strengths
- Hazard mapping is based on a formal study evaluating both the probability and intensity of phenomena.
- Areas protected by structures are included, reflecting real-world risk scenarios of failure or inadequacy.
- Data is compiled from multiple sources of calculated, modelled, or observed hazard data.
Limitations
- Last updated 2019-04-26 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- The underlying source hazard data is not included in this dataset.
