PPRI Vézère: Flood Risk Prevention Plan Regulatory Zoning for the Vézère Basin

The Vézère en Corrèze river basin in France is covered by this dataset. It contains isocotes (contour lines) representing the regulatory zoning for the Flood Risk Prevention Plan (PPRI), standardized in 2016 based on source layers from 2002. The data was published by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated in January 2022.

Use Cases

• Mapping flood-prone areas based on the regulatory zoning isocotes.
• Analyzing changes in flood risk planning by comparing the 2016 standardization with the original 2002 layers.
• Supporting land-use planning and development restrictions using the PPRI regulatory boundaries.

Strengths

• Data is standardized to the Covadis national geographic data standard, which likely ensures interoperability.
• The associated PPRI plan has a specific approval date (25/10/2016), providing a regulatory reference point.
• Last update was recorded on 2022-01-14, indicating some level of maintenance.

Limitations

• The description notes the layers did not benefit from a recaling (re-scaling) performed in 2018 on the regulatory zoning table, suggesting potential alignment or accuracy issues.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
