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

The dataset provides a 10-meter uncertainty band for the regulatory flood risk prevention plan (PPRi) in the Vitry-le-François — Marne-Blaise sector. The data was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated on April 4, 2019. It stems from hazard studies mapped at a 1/10,000 scale, with the uncertainty band indicating the limits of precision for the regulatory zoning contours.

Use Cases

• Assessing the precision limits of regulatory flood maps based on the described 10-meter uncertainty band.
• Transposing hazard zoning into urban planning documents (PLU) based on the principles and guidance mentioned in the description.
• Evaluating land-use restrictions for planning permissions based on the described area regulations and uncertainty at zone boundaries.

Strengths

• Originates from a specific geological and mining research organization (BRGM).
• Explicitly defines a 10-meter uncertainty band for hazard contours, providing a measure of data reliability.
• Based on studies conducted at a defined 1/10,000 scale.

Limitations

• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description advises against using the data at a cadastral scale (1/5000 or 1/2000), limiting its application for highly detailed parcel-level analysis.
