PPRi de Châlons-en-Champagne: 10-Metre Uncertainty Band for Flood Hazard Zoning

A 10-metre uncertainty band for flood hazard zoning in Châlons-en-Champagne, France, created by the Bureau de Recherches Géologiques et Minières. The data originates from hazard studies mapped at a 1/10,000 scale and was last updated in April 2019. The band represents areas where regulatory zone boundaries are not precisely defined due to inherent data accuracy limits.

Use Cases

• Assess the impact of mapping uncertainty on land-use planning decisions based on the described 10-metre uncertainty band.
• Guide the transposition of regulatory flood zones into municipal planning documents based on the principles outlined in the dataset's accompanying guide.
• Define appropriate regulations for planning permission applications in areas near zone boundaries based on the uncertainty band's interpretation.

Strengths

• Explicitly defines a 10-metre uncertainty band for flood zone boundaries, providing a concrete measure of spatial accuracy.
• Includes a guide detailing operational principles for municipalities to use the data in urban planning documents.
• Based on hazard studies conducted at a defined 1/10,000 scale.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
