France's PPRI Epte dataset maps areas exposed to one or more natural hazards for risk prevention planning. The data, compiled by the Bureau de Recherches Géologiques et Minières, represents hazard zones based on studies assessing the probability and intensity of dangerous phenomena. It was last updated on September 17, 2021.
Use Cases
- Delineating regulatory hazard zones based on the probability and intensity of dangerous phenomena.
- Assessing areas protected by structures that are still considered subject to hazard.
- Identifying 'zero or insignificant hazard zones' where studied hazards are nil.
- Supporting multi-hazard risk analysis by integrating zones exposed to several hazards.
Strengths
- Hazard zones are defined by a specific methodology evaluating both probability of occurrence and degree of intensity.
- Areas protected by structures are included, accounting for potential breakage or inadequacy.
- The dataset is compiled from several sources of calculated, modelled, or observed hazard data.
Limitations
- Last updated 2021-09-17 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
