PPRN: Natural Hazard Prevention Plan Maps for Lanoux Municipality

The COVADIS standard provides a framework for storing geographical data from French Risk Prevention Plans (PPRs). These plans, established under the 1995 Act, map regulatory zones, hazard intensities, and identified issues for eight natural and four technological risks. The data standard aims for homogeneous storage across ministries responsible for agriculture and ecology.

Use Cases

• Mapping regulatory zones for land development based on hazard exposure levels described in the plan.
• Analyzing spatial overlap between different natural hazards like floods and forest fires.
• Assessing the distribution of identified issues (e.g., infrastructure) relative to hazard intensity maps.
• Standardizing the storage and exchange of risk prevention plan data between government departments.

Strengths

• Data conforms to the COVADIS standard, promoting interoperability across government ministries.
• Plans are established by the State and decided by the Prefect, indicating an authoritative source.
• Covers a defined set of eight main natural hazards and four technological risks.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The scope is limited to geographical data and does not model the complete risk prevention plan dossier.
