Plan for the prevention of natural flood hazards — Municipalities of the Garonne sector upstream — Perimeter — Department of Tarn-et-Garonne

This dataset contains the boundaries at the different stages of the PPRN; development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a defined date. It is: — prescribed perimeter set out in the prescribing order of n°#x27; a PPR (natural or technological); — perimeter d' exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is a public utility easement (PM1 for PPRNs and PM3 for PPRTs); — perimeter d' study corresponding to #x27; envelope in which hazards have been studied. __Origin__ The perimeter of a prescribed PPR is usually provided in the prefect’s prescription order. The perimeter d' exposure to risks — or regulated perimeter — corresponds to the \#x27; geometric aggregation of l' all the restricted zones listed in the same PPR. The perimeter of the study corresponds to the envelope in which the hazards were studied. __Partner organisations__ DDT Tarn-et-Garonne __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-8f26f672-11d1-476c-862f-522d31acf20c) * [documentation of the VAlidation Data Commission Data Standard for Spatialised Information (COVADIS): Natural and Technological Risk Prevention Plan](http://www.geoinformations.developpement-durable.gouv.fr/standard-de-donnees-covadis-plan-de-prevention-des-a2140.html) * [COVADIS data standard: Scope of PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_PERIMETRE_PPRN_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/6a076bdedc0c91386e1ae8eea892348b7cdbddc0)
