Montdidier PPRM hazard zone data represents areas exposed to one or more hazards as defined for risk analysis. The dataset was published by the Bureau de Recherches Géologiques et Minières and was last updated on March 25, 2019. It contains hazard zones resulting from a synthesis of calculated, modelled, or observed hazard data.
Use Cases
- Mapping flood or landslide risk zones based on the described hazard level zoning.
- Assessing land use suitability for construction based on identified hazard exposure areas.
- Modeling the impact of protective structures on hazard exposure, as mentioned in the description.
- Analyzing multi-hazard overlaps where zones are identified by codes for each hazard.
Strengths
- Data is produced by a recognized geological and mining research bureau (BRGM).
- Hazard zoning is graduated according to the level of hazard, incorporating probability and intensity.
- Areas protected by structures are included, accounting for potential failure scenarios.
Limitations
- Last updated 2019-03-25 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and specific file formats are unknown, which may limit suitability assessment.
