Perimeter of the Plan to prevent the foreseeable natural risks of flooding of the Loire on the Val de Bréhémont — Langeais in the Indre-et-Loire

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. This is the:- prescribed perimeter listed in the prescribing order of #x27; a PPR (natural or technological);- perimeter of #x27; exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is equivalent to easement of public utility (PM1 for PPRNs and PM3 for PPRTs);- perimeter of #x27; study corresponding to the #x27; envelope in which the hazards have been studied. __Origin__ Geometric modelling depends on the type of l' challenge and its modeling in the data source or geographical repository from which it comes. A stake is usually represented by a polygon, a polyline, or a point with a spatial resolution sufficient to appreciate s' it is concerned by one or more zones of #x27;aira. __Partner organisations__ DDT Indre-et-Loire __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-e8279332-6d72-45cb-9b7f-b8820217469c) * [COVADIS data standard: One-time issue of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ENJEU_PPRN_AAAANNNN_P) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/0dc18dc5b50c148e1c35cb06ef85f8ac4cdd324a)
