Regulated Areas of the PPRT Primagaz: French Risk Prevention Plan Zoning

A 2021 geospatial dataset from the French Geological Survey (BRGM) describing regulated land-use zones under an approved Risk Prevention Plan (PPR). It categorizes areas into construction ban zones (red), zones subject to requirements (blue), and other regulated parcels. The data is served via a Web Map Service (WMS) for visualization and integration.

Use Cases

• Assess land development suitability based on designated hazard zones.
• Visualize spatial restrictions for construction permits using the categorized zoning data.
• Integrate regulatory zoning layers into municipal planning and risk management systems.

Strengths

• Data is produced by a national geological survey (BRGM), suggesting authoritative sourcing.
• The description provides clear definitions for three regulatory zone types (red, blue, other).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-03-22 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
