Saint-Vaast La Hougue PPRL Hazard Zones for Risk Analysis

Hazard zones for the Saint-Vaast La Hougue area, representing areas exposed to one or more hazards as defined by the RPP risk analysis. The dataset was created by the Bureau de Recherches Géologiques et Minières and last updated on April 27, 2021. Hazard levels are graduated based on the probability and intensity of dangerous phenomena.

Use Cases

• Delineating land-use restrictions based on hazard zoning levels described in the dataset.
• Modeling risk exposure for infrastructure planning using the graduated hazard intensity zones.
• Integrating hazard data with protective structure locations, as areas behind structures are included.
• Identifying 'no or insignificant hazard zones' for development suitability analysis.

Strengths

• Data is based on a synthesis of multiple sources of calculated, modelled, or observed hazard data.
• Includes areas protected by structures, which are explicitly considered subject to hazard.
• Hazard zoning is graduated according to the level of hazard, providing detail beyond binary classification.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-04-27 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
