Geospatial layers materialize noise-affected areas alongside national road sections in France. The dataset implements a 1996 ministerial order defining five noise categories and sector widths for land transport infrastructure. The Bureau de Recherches Géologiques et Minières published this data, last updated in January 2022.
Use Cases
- Classify land transport infrastructure noise levels based on the five defined categories.
- Define minimum acoustic isolation requirements for new sensitive buildings based on their location in noise-affected sectors.
- Map the width of noise-affected sectors on both sides of road sections for environmental management.
Strengths
- Implements a specific 1996 ministerial order defining five noise categories.
- Geospatial layers directly represent legally defined noise-affected areas.
- Last update recorded on 2022-01-11.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
