BRGM's 2019 hazard zoning maps delineate coastal cliff areas exposed to natural risks for regulatory planning. The dataset likely contains graduated hazard zones, considering probability and intensity of dangerous phenomena, including areas protected by structures. Hazard zones are compiled from multiple sources of calculated, modelled, or observed hazard data.
Use Cases
- Risk assessment modeling based on graduated hazard zoning levels.
- Land-use planning and regulatory zoning based on hazard exposure maps.
- Identifying areas protected by structures that are still considered subject to hazard.
- Analyzing coastal cliff vulnerability based on probability and intensity of phenomena.
Strengths
- Hazard zones are compiled from multiple sources of calculated, modelled, or observed data.
- Includes areas protected by structures, which are always considered subject to hazard.
- Zoning is graduated according to the level of hazard, incorporating probability and intensity.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2019-04-01; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
