Type B maps of areas affected by road noise in Côte-d’Or

These maps, also referred to as ‘type B cards’, represent the ‘areas affected by noise’ adopted by the Prefect pursuant to Article R571-37 of the Environmental Code on the sound classification of tracks. __Origin__ The noise levels emitted by a given infrastructure during an average day are evaluated using numerical models producing isophone curves translated into noise zones, according to the; index recommended for all modes of transport at European level, namely the Lden index and l' index Ln.The isophone curves, described by the resource N_BRUIT_ISOPHONE_L thus serve to delimit the external borders and, where appropriate, internal noise zones by range of #x27; indices. __Partner organisations__ DDT Cher, DDT Côte-d'Or __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-8ab88d20-4f63-4d0f-8042-953c6e367d51) * [COVADIS data standard: Table describing Noise Areas of (to be completed)(http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_BRUIT_ZBR_INFRA_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/ceeb2852962fc371170d8206c8514ffda889602d)
