Landes Department Noise Maps for Agglomerations and Roads Exceeding 68 dB(A)

Noise maps for the Department of Landes, France, produced in 2008 in response to national decrees implementing European noise control policy. The maps show zones where harmonized noise level indicators Lden (day-evening-night) exceed 68 dB(A) and Ln (night) exceed 62 dB(A). Data was created by the Bureau de Recherches Géologiques et Minières and last updated in 2021.

Use Cases

• Assess population exposure to harmful noise levels based on the Lden and Ln indicators.
• Plan noise mitigation strategies for agglomerations and major transport corridors.
• Evaluate compliance with European and French environmental noise regulations.
• Model noise propagation from specific road networks, including the A63, A64, and RN10.

Strengths

• Maps are based on four harmonized noise level indicators (Lden, Ln, Lden >68 dB(A), Ln >62 dB(A)) for consistent assessment.
• Covers specific, named infrastructure including motorways (A63, A64), national roads (RN10), and departmental roads.
• Produced by a recognized geological and mining research organization (BRGM).

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.
• Column-level documentation is absent; field semantics must be inferred after download.
