Risk — 41DDT20060003 Perimeter of PPR R111.3 TROO field movement in Loir-et-Cher

This dataset contains the boundaries of the PPR. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a defined date. This is the prescribed perimeter set out in the prescribing order of n°#x27; a PPR (natural). This approved perimeter is equivalent to servitude of public utility (PM1). __Origin__ The study was carried out by the companies Certio and Apave, the CETE of Lyon and CEREMA. Sound levels were obtained by calculation (and not by acoustic measurements) from the modelling of the infrastructure and its surrounding environment, in accordance with the Order of 4 April 2006. The method used refers strictly to the recommendations of the SETRA &quot Methodological Guide;Production of strategic noise maps of major roads and railways;. 1. Creation of a 3D digital model from noise sources, built and terrain 2. Calculate noise exposure levels in the study area 3. Crossover of data obtained from the first two phases. __Partner organisations__ 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-d886d442-9bef-4784-acec-3ce012d4046a) * [COVADIS data standard: Risk Prevention Plan PPRN PPRT](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?id=15) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/78ce3a33456a3cd256f67c1a379cae5f2141b043)
