Saint Viance PPRMT Regulatory Areas 2009: Natural Risk Zoning for Land Movements

Saint Viance PPRMT Regulatory Areas 2009 — Corrèze is a geospatial dataset from the Bureau de Recherches Géologiques et Minières (BRGM). It contains the regulatory zoning for the Plan for the Prevention of Natural Risks of Field Movements (PPRMT) in the northwest sector of the commune of Saint-Viance, approved on 3 November 2009. The data defines hazard zones based on geological formations, hydrogeology, and morphology.

Use Cases

• Assess land constructibility based on hazard intensity zones defined in the PPRMT.
• Map areas of medium and strong hazard for soil instability as described in the regulatory analysis.
• Apply specific land-use regulations for new constructions in designated blue and orange zones.
• Analyze the relationship between geological formations, hydrogeology, and defined risk areas.

Strengths

• Dataset is based on a formally approved regulatory plan (PPRMT) dated 3 November 2009.
• Hazard analysis incorporates specific factors: geological formations, hydrogeology, and morphology.
• Regulatory mapping defines three distinct hazard zones with specific construction rules.

Limitations

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