Strategic noise maps for terrestrial transport infrastructure in the Charente department of France. Data includes 24-hour and night-time weighted average sound level maps exceeding specific decibel thresholds, as well as sound classification maps for roadways and railways. The dataset was published by the Bureau de Recherches Géologiques et Minières and was last updated on March 17, 2021.
Use Cases
- Modeling noise exposure for public health studies based on 24-hour and night-time sound level maps.
- Assessing compliance with noise regulations using maps of limit values.
- Planning noise mitigation measures for transport infrastructure based on sound classification maps.
- Analyzing spatial distribution of noise pollution in the Charente region.
Strengths
- Maps are categorized by specific noise assessment types (A, B, C, D) as defined in the description.
- Includes data for sound levels exceeding defined thresholds (e.g., >55 dB(A) for 24h averages).
- Covers the specific geographic area of the Charente department in France.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2021-03-17 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
