Natural Risk Prevention Plan — commune Lauzun — Lot-et-garonne: Surface perimeters

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 boundaries of a restricted zone are represented on the graphical documents of the PPR. Regulatory limits are generally set on natural phenomena, which do not follow cadastral or administrative boundaries. A PPR determines the boundaries of the different restricted zones according to the calculated right-of-way of hazardous phenomena. The publication of the standard took place after the PPR procedure was time-barred. The master responsible for managing the PPR decided to take over the file to produce the data in COVADIS format. This production may include the retrieval of pre-existing geographical data as part of digitisation.This metadata may be usefully supplemented by the characteristics specific to the datasets obtained by indicating whether the quality recommendations (B.4) of the standard have been complied with or possibly measured, and specifying any technical limitations caused by the procedure used. The opposable PPRN is a paper document. During the digitisation of the route, the contour was recalibrated on the cadastral plane of the DGFiP while respecting the original contour at best. __Partner organisations__ DDT 47 (Departmental Directorate of Lot and Garonne Territories), DDT Lot-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-f51afe17-fdc8-419e-beb8-c22ce16726f0) * [COVADIS data standard: Restricted zone of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/56fc247cc0be75c839b1991a715f59142d627be8)
