N_SECTOR_CC_45002_045.TAB

The code of urban planning defines two types of sectors for municipal maps: constructible and inconstructible sectors. However, there are special cases: — Graphical documents may define sectors reserved for industrial or craft activities, in particular those incompatible with the neighbourhood of inhabited areas. — They delimit, where applicable, the sectors in which reconstruction at the same time as #x27; a building destroyed by a disaster no. #x27; is not allowed. — Installations necessary for collective facilities, for agriculture or forestry and for the development of natural resources are not covered by the principle of inconstructibility resulting from classification. The areas of the municipal map do not always cover the whole of the communal territory. The areas of the municipality not covered by a sector are represented by an object to cover the whole municipality. __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 Loiret __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-78f7094f-b978-475d-b802-0c731527d8d6) * [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/df82a199dd645772283ee23573a654e57d91a24e)
