Map Viewing Service (WMS) of the dataset: Noise zones of a strategic noise map of type A, associated index Ln, on the road network of Upper Corsica

Noise zones describe a noise exposure situation based on a noise indicator or area affected by noise. They are used primarily for the preparation of strategic noise maps pursuant to Article R.572-5 of the Environmental Code. Noise zones are geometric elements of the strategic noise map. For type A maps (CBSTYPE), each noise zone is usually bounded by 2 isophone curves (Lden 55-60, 60-65, 65-70, 70-75 and Ln 50-55, 55-60, 60-65, 65-70) or by the lower limit isophone curve (Lden >75, Ln > 70).
