Agglomeration Noise Maps: Sound Level Zoning for Day, Evening, and Night in Landes, France

2008 noise maps for the Department of Landes, France, produced by the Bureau de Recherches Géologiques et Minières in response to European Directive 2002-49 and a 2006 French decree. The data includes four families of noise maps based on harmonized indicators Lden and Ln, covering major road, motorway, and railway infrastructure. The dataset was last updated in the platform's catalog on September 17, 2021.

Use Cases

• Assess compliance with EU noise directive thresholds based on Lden and Ln indicators.
• Model noise exposure for populations near specified motorway and road networks.
• Plan infrastructure development or noise barriers using the 2008 zoning diagnosis.
• Compare noise levels across different times of day (day, evening, night) for environmental impact studies.

Strengths

• Based on specific legal frameworks: European Directive 2002-49 and French Decree No. 2006-361.
• Covers four distinct noise level indicators (Lden, Ln, Lden >68 dB(A), Ln >62 dB(A)) for a detailed diagnosis.
• Explicitly lists the motorway (A63, A64), national (RN10), and departmental road networks included in the 2008 analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-09-17; freshness should be verified as the underlying data is from 2008.
• Row count and file formats are unknown, which may limit suitability assessment.
