Characteristics of the PPRI of the Poses Loop

Characteristics of the PPRI of the Poses Loop __Origin__ Type A and C noise maps are produced from computer modelling of influential sources of noise and their spread within the territory. The data required for the production of noise maps are divided into three categories: — emission data: relating to the source of noise studied; — propagation data: relating to the land; — exposure data: related to the population. The repository used for geometric data is Lambert 93. The geometric data used, mainly from IGN, are as follows: — BD TOPO3D® IGN. — The population data used are from INSEE (2016 squared data). The maps were made using Mithra-SIG ® version 5 noise forecasting software. integrates these calculation methods. __Partner organisations__ DDTM Eure, Territorial Monitoring Workshop __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-aedeca2c-6094-461b-a6a8-499c8df1c0c7) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/844c3dba7d406e6402a5562160df99adfca069e6)
