Risk origin data characterizes real-world entities that represent potential hazards, such as rivers or geologically unstable areas. The dataset is produced by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on September 14, 2021. It underpins the definition of risk-exposed areas for the Flood Risk Prevention Plan (PPRi) in the Loire Valley, specifically the Orléans area.
Use Cases
- Mapping flood risk sources based on the location of hazardous entities like rivers.
- Defining risk-exposed areas for regulatory planning based on the described origin of risk.
- Analyzing the spatial relationship between hazard origins and populated zones mentioned in the description.
Strengths
- Produced by a recognized geological and mining research organization (BRGM).
- Explicitly linked to a formal regulatory framework (Flood Risk Prevention Plan - PPRi).
- Last update date is precisely recorded as 2021-09-14.
Limitations
- Row count and dataset scale are unknown, limiting suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Freshness should be verified as the data was last updated in 2021.
