Natural Flood Risk Prevention Plan for Val de Léré-Bannay and La Celle-sur-Loire, Nièvre

A geospatial dataset representing the Natural Flood Risk Prevention Plan (PPRi) for the Val de Léré-Bannay and La Celle-sur-Loire areas in the Nièvre department of France. The data standard, established by COVADIS, provides specifications for storing geographical data from risk prevention plans, which are regulatory instruments established under French law. The dataset was last updated on August 13, 2020, and is managed by the Bureau de Recherches Géologiques et Minières.

Use Cases

• Delineate regulated zones for construction based on flood hazard levels described in the plan.
• Map flood hazard intensity levels using the hazard documents referenced in the description.
• Identify and analyze assets and infrastructure at risk using the 'issues' maps mentioned.
• Standardize storage and exchange of PPR geographical data across ministries as per the COVADIS standard.

Strengths

• Based on the national COVADIS data standard for risk prevention plans, ensuring interoperability.
• Explicitly covers three categories of information: regulatory mapping, hazard documents, and identified issues.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2020-08-13 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
