Plan for the prevention of natural hazards of landslides — Commune de Piquecos — 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__ This table is rendered geometrically using the IAL perimeter (prescription perimeter when the PPR is prescribed or perimeter regulated when the PPR is approved).The geometry of the prescribed perimeter of {\#x27; a PPR is provided by the prefectural prescription order of this PPR. The geometry of the regulated perimeter of a PPR is constructed by l' geometric aggregation of polygons representing the zones restricted by the PPR.Source of georeferencing: Scan25 (IGN) 2009, for prescribed PPRsThematic source: — List of prescribed and approved PPRNs on the department based on existing information in the; GASPAR application for monitoring PPR procedures. __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-4266f063-46de-4de4-acea-bcbe15e137d8) * [COVADIS data standard: PPRN document on the department...](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_DOCUMENT_PPRN_S) * [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) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/a2b8e3ee043c522f2f26aaf782b3b0b697e72925)
