Landslide Hazard Zones for the Puycornet Municipality, Tarn-et-Garonne, France

Geospatial hazard zones for landslide risk prevention in the Municipality of Puycornet, Tarn-et-Garonne, France. The dataset was published by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on September 12, 2022. It represents areas exposed to landslides, as defined by a multi-hazard risk analysis, with zones graduated according to hazard intensity and probability.

Use Cases

• Mapping areas for development restrictions based on landslide hazard zones described in the risk plan.
• Modeling multi-hazard exposure by integrating zones identified with codes for each hazard type.
• Assessing the adequacy of protective structures by analyzing areas represented as subject to hazard despite existing works.
• Identifying 'no or insignificant hazard zones' for comparative land-use planning within the study perimeter.

Strengths

• Hazard zones are defined by a specific study assessing intensity and probability of occurrence at any point.
• Includes areas protected by structures, which are still considered subject to hazard, providing a conservative risk view.
• Data is compiled from a synthesis of multiple calculated, modelled, or observed hazard data sources.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
