Landes Department Noise Maps: Day, Evening, and Night Sound Level Zoning from 2008

The Department of Landes in France produced these noise maps in 2008 in response to European and French environmental noise directives. The data represent an initial diagnosis using four harmonized noise level indicators, including Lden and Ln, for major road and motorway infrastructure. The dataset was last updated on the platform in September 2021 by the Bureau de Recherches Géologiques et Minières.

Use Cases

• Assess compliance with EU noise directive thresholds based on Lden and Ln indicators.
• Model population exposure to transportation noise based on zoning around specified road networks.
• Plan noise mitigation strategies for agglomerations based on 2008 baseline sound level data.

Strengths

• Data is based on specific legal thresholds from Decree No. 2006-361, providing a clear regulatory context.
• Maps cover four distinct noise indicators (Lden, Ln, Lden >68 dB(A), Ln >62 dB(A)) for a multi-faceted analysis.
• The geographic scope is precisely defined, covering the motorway (A63, A64), national (RN10), and departmental road networks in Landes.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-09-17 00:00:00; freshness should be verified as the underlying data is from 2008.
• Column-level documentation is absent; field semantics must be inferred after download.
