PPRI Vézère Basin: Flood Risk Prevention Plan Regulatory Zoning Isocotes

Isocotes of the regulatory zoning for the Flood Risk Prevention Plan (PPRI) of the Vézère en Corrèze basin. The data was standardized to the Covadis standard in 2016 based on assembled PPRI layers supplied in 2002. The Bureau de Recherches Géologiques et Minières (BRGM) published an update on 2022-01-14.

Use Cases

• Mapping flood risk zones based on regulatory isocotes.
• Assessing compliance with land-use regulations in flood-prone areas.
• Integrating historical flood plan data (2002) with modern geospatial standards (Covadis 2016).
• Analyzing spatial patterns of regulatory constraints for development planning.

Strengths

• Data adheres to the Covadis geospatial standard, promoting interoperability.
• Plan has a formal approval date (25/10/2016), indicating regulatory status.
• Last metadata update was 2022-01-14, suggesting some maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying 2002 PPRI layers did not benefit from a 2018 recaling, potentially affecting alignment with newer data.
• Row count and dataset size are unknown, which may limit suitability assessment.
