Vitry-le-François PPRi: 10-Meter Uncertainty Band for Flood Hazard Zoning

The Bureau de Recherches Géologiques et Minières provides a Web Map Service (WMS) depicting a 10-meter uncertainty band for the flood risk prevention plan (PPRi) in the Vitry-le-François — Saulx sector. The regulatory zoning is derived from hazard and stake maps created at a 1/10,000 scale, with an inherent positional uncertainty of about 10 meters. This dataset was last updated on September 9, 2022.

Use Cases

• Visualizing the spatial uncertainty of flood hazard zones based on the described 10-meter contour uncertainty.
• Assessing the suitability of regulatory flood maps for cadastral-scale planning based on the described 1/10,000 scale limitation.
• Informing municipal transposition of hazard maps into urban planning documents based on the described operating principles guide.

Strengths

• The dataset explicitly defines a 10-meter uncertainty band for hazard zone contours.
• The data is provided via a standardized Web Map Service (WMS) for direct geospatial integration.
• The description details a specific operational scale of 1/10,000 for intended use.

Limitations

• The description metadata is limited; actual data quality and column definitions require manual inspection after access.
• Last updated 2022-09-09 00:00:00; freshness should be verified for current planning applications.
• The dataset is explicitly not recommended for use at cadastral scales finer than 1/10,000, limiting detailed parcel-level analysis.
