BUTAGAZ PPRT Hazard Zones in Douhet, Charente-Maritime

A Web Map Service (WMS) layer delineating areas exposed to hazards for the BUTAGAZ industrial facility in Douhet, France, published by the Bureau de Recherches Géologiques et Minières. The hazard map results from a risk analysis study, grading zones by the probability and intensity of dangerous phenomena. The data was last updated on September 17, 2021.

Use Cases

• Risk assessment and land-use planning based on the graduated hazard zoning.
• Emergency response planning based on the aggregated hazard synthesis map.
• Environmental impact studies based on the representation of areas protected by structures that are still considered at risk.

Strengths

• Hazard zones are defined by a formal study evaluating probability and intensity of phenomena.
• The map includes areas behind protective structures, accounting for potential failure.
• Data is provided via a standardized Web Map Service (WMS) for integration into GIS platforms.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after access.
• Last updated 2021-09-17 00:00:00; freshness should be verified for current risk assessments.
• The specific hazard types, calculation methods, and source data are not detailed in this metadata.
