Hazard area data for the Saint-Vaast La Hougue region, representing zones exposed to one or more natural hazards as defined for Risk Prevention Plans (PPR). The dataset was published by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on April 27, 2021. It includes areas where hazard intensity has been assessed, considering the probability and intensity of dangerous phenomena.
Use Cases
- Modeling flood or coastal erosion risk based on described hazard intensity zoning.
- Informing land-use regulations and construction permits based on mapped hazard areas.
- Assessing the impact of protective structures on hazard exposure, as mentioned in the description.
- Integrating multi-hazard risk analysis for the study area, as the description references multi-random PPRNs.
Strengths
- Data is derived from a synthesis of multiple calculated, modeled, or observed hazard data sources.
- Hazard zones are defined with consideration for both the probability of occurrence and the intensity of phenomena.
- Areas protected by structures are included, accounting for potential failure.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2021-04-27 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
