Dataset Direct Download Service (WFS): Noise in the Environment — Strategic Noise Mapping in the Gers Department — Assembling of data for road infrastructure — 3 rd deadline 2017/2022 — Type B map

Noise maps are defined by Article L.572-3 of the Environmental Code. The lot contains the geographical data of the noise zones, they are interoperable in accordance with Directive 2002/49/EC of 25 June 2002, transposed into French law by Articles L.572-1 to L.572-11 of the Environmental Code. Noise level 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. The noise levels emitted by a given infrastructure over an average day are assessed using numerical models producing isophone curves translated into noise zones, according to the recommended index for all modes of transport at European level, i.e. the Lden index and the Ln index.
