Map Viewing Service (WMS) of the dataset: Strategic noise map type C according to the Lden indicator (evening day-night) of the network in Loire-Atlantique
Description
Type ‘c’ map showing the exceedance areas of the limit value defined for railway infrastructure in Ln, noise indicator in Lden, noise indicator during day-night-night period, 68 dB(A) — Decree of 11/12/2018.
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 shares the lower limit isophone curve (Lden >75, Ln > 70).
For type C maps (CBSTYPE), each noise zone shall be bounded by the lower limit isophone curve (Lden > 68 or 73, Ln > 62 or 65).
