Dataset Direct Download Service (WFS): Aggregation road noise zones type A, index D — Alpes de Haute-Provence

Maps to be produced in the framework of the Strategic Noise Cards (CBS) pursuant to Article 3-II-1°-a of the Decree of 24 March 2006 and the European Directive 2002/49/EC on the management of environmental noise. Noise maps are not prescriptive. Aggregation of GIS layers describing the Noise Zones for Road Networks (R) for the Type A map and LD index. Approved by prefectural decree of 08/08/2018. Road infrastructure concerned: A51, RN85, RD4, RN4a, RD4b, RD4085, RD4096, RD907 ‘Type a’ exposure cards: These are two cards representing the year in which the cards were drawn up: — areas exposed to more than 55 dB(A) in Lden. They represent the isophone curves of 5 in 5 dB(A). Lden: sound level indicator means Level Day-Evening-Night. It corresponds to an equivalent 24-hour sound level in which evening and night noise levels are increased by 5 and 10 dB(A), respectively, to reflect greater discomfort during these periods. The layers are produced by road axis in accordance with the COVADIS standard validated on 29 May 2017. Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA. Data source by infrastructure: CEREMA and VINCI for A51 Strategic noise maps are reviewed every 5 years
