DDT 70: Strategic Noise Map for Haute-Saône, France

A strategic noise map for the Haute-Saône department in France, last updated on 2019-03-28. It was created by the Bureau de Recherches Géologiques et Minières (BRGM) to fulfill the requirements of the European Directive 2002/49/EC on environmental noise assessment. The map represents noise exposure using defined noise indicators and zones bounded by isophone curves.

Use Cases

• Assessing population exposure to environmental noise based on defined noise indicators (Lden, Ln).
• Informing Local Urban Planning Plans (LDP) by providing graphic elements on noise situations.
• Establishing baselines for Urban Travel Plans (UDP) to identify areas needing better traffic management.
• Analyzing noise zone geometries bounded by specific isophone curves for type C maps.

Strengths

• Created for compliance with a specific European Directive (2002/49/EC), providing a legal context.
• Defines noise zones using specific isophone curve thresholds (e.g., Lden > 68 or 73, Ln > 62 or 65 for type C maps).
• Associated with a specific geographic area (Haute-Saône department).

Limitations

• Last updated 2019-03-28; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
