Reference profiles for regulatory zoning in the Vitry-le-François Marne sector, created by the Bureau de Recherches Géologiques et Minières. The profiles visualize water heights from hydraulic modeling of centennial flood hazards, with altimeter deviations of about 20 cm linked to the General Leveling of France. The dataset was last updated on December 8, 2023.
Use Cases
- Determine regulatory construction heights based on reference profiles increased by 5 cm or 30 cm as defined in the by-law.
- Visualize centennial flood hazard water levels across the sector for risk mapping.
- Locate reference ratings upstream of a site for compliance with zoning maps.
- Assess flood vulnerability for habitable surfaces and electrical installations using the defined regulatory ratings.
Strengths
- Profiles are linked to the General Leveling of France (NGF), providing a standardized vertical reference.
- Altimeter deviation is specified as about 20 cm, indicating a defined precision level.
- Regulatory ratings are explicitly defined with specific increments (5 cm and 30 cm) for different construction types.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update was 2023-12-08.
