Surface Entity Origins for Blaise River Flood Risk in Eure-et-Loir, France

A 2022 geospatial dataset from the Bureau de Recherches Géologiques et Minières (BRGM) identifying real-world entities that represent a potential flood risk for the Blaise river in the Eure-et-Loir department (28) of France. The data characterizes origins of risk, such as rivers or unstable geological areas, which are used to define risk-exposed areas for flood prevention plans (PPRN). It is served via a Web Map Service (WMS) for visualization.

Use Cases

• Mapping flood risk origins based on the described geographical objects like rivers.
• Defining risk-exposed areas (risk pools) for regulatory flood prevention plans (PPRN) based on the location of hazardous entities.
• Analyzing the spatial relationship between natural features and flood risk zones for the Blaise river catchment.

Strengths

• Data is provided by a recognized geological and mining research organization (Bureau de Recherches Géologiques et Minières).
• Specific geographic focus on the Blaise river in the Eure-et-Loir department (28).
• Explicitly supports the definition of regulatory risk-exposed areas (PPRN).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last updated 2022-05-17 00:00:00; freshness should be verified for current risk assessments.
