Hazard zones for the Multi-Risk Prevention Plan (PPRN-MT) of Bessancourt, France, delineating areas exposed to one or more natural hazards based on intensity and probability assessments. The dataset was created by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on September 17, 2021. It represents the compiled hazard map used for regulatory risk analysis, including areas protected by structures that are still considered subject to hazard.
Use Cases
- Delineating regulatory building restrictions based on hazard intensity and probability levels mentioned in the description
- Modeling multi-risk exposure for insurance or emergency planning based on the hazard zoning methodology
- Integrating hazard zones with other geospatial data for land-use planning, as the data excludes 'zero hazard' areas
Strengths
- Data is produced by a recognized geological and mining research organization (Bureau de Recherches Géologiques et Minières).
- The hazard zoning methodology is explicitly described, considering both probability of occurrence and intensity of phenomena.
- Includes areas behind protective structures, acknowledging cases of structural failure or inadequacy.
