A dataset from the Bureau de Recherches Géologiques et Minières (BRGM) characterizes entities that pose natural hazards, such as watercourses or unstable geological areas. The location of these entities and the associated dangerous phenomena are used to define risk-exposed areas underpinning Risk Prevention Plans (PPRi). The dataset was last updated on May 17, 2021.
Use Cases
- Mapping flood risk zones based on the location of watercourses mentioned in the description.
- Identifying areas susceptible to landslides based on the location of geologically unstable areas.
- Defining risk pools for Risk Prevention Plans (PPRi) based on the location of hazard entities.
- Analyzing the spatial relationship between hazard origins and exposed assets.
Strengths
- Produced by the Bureau de Recherches Géologiques et Minières (BRGM), a recognized geological survey.
- Focuses on concrete risk origins like watercourses and unstable geological areas.
- Supports the definition of official Risk Prevention Plans (PPRi).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2021-05-17 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
