Fishing — Organic tanks on the Loire Basin — Brittany

Biological reservoirs on the Loire Basin — Brittany __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 the Ln index. The isophone curves, described by the resource N_BRUIT_ISOPHONE_L, are thus used to delimit the external and, where appropriate, internal boundaries of noise zones by ranges of d' indices. __Partner organisations__ DDT Tarn-et-Garonne, DDT Loir-et-Cher __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-f7bd8371-086b-4cb1-8af6-67e0f2ea0092) * [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/afe98e0c537ee61fd9820c49f1b254282e861a99)
