SUP_T1 — Protective areas (Railways)

The Risk Prevention Plans (RPPs) were established by the law of 2 February 1995 on strengthening the protection of the environment. They constitute the essential instrument of the State in the field of risk prevention. Their objective is to control the development in areas exposed to a major risk.The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through construction bans or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices...).The plans may be in progress; preparation (prescribed), applied in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a regulation. Can be attached d' other graphic documents useful for understanding the approach (hazards, challenges...). Each PPR shall be identified by a polygon corresponding to the prescribing perimeter set of municipalities concerned when it is at the prescribed state; and l' envelope of restricted zones when it is at the approved state. This geographic table makes it possible to map existing PPRTs on the department.Each PPRT document in the geographic table N_DOCUMENT_PPRT is linked to the \#x27;using its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the number d' order of the PPR procedure associated in GASPAR): 1. to its administrative procedure d' elaboration (or revision) managed in #x27; GASPAR application, d' on the one hand, to its series of numeric geographic constituent data described by the metadata sheet N_PPRT_AAAANNNN (#0001496) d' on the other hand. __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:- cadastral reference PCI (DGFIP) or BD Parcellar (IGN) name, version and news to be specified- Scan25 (IGN): number and year of l' edition to be specified- BD CARTO (IGN) or GeoFLA (IGN) (number and year of l' edition to be specified) for prescribed PPRs — List of prescribed and approved PPRTs on the department based on existing information in the; GASPAR application for monitoring PPR procedures. __Partner organisations__ DDT Val-d'Oise, DDT95 — Risk and noise cluster __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-cd05bf02-4c2b-47f6-bf83-a61bfeae8452) * [COVADIS data standard: Risk Prevention Plan PPRN PPRT](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?id=15) * [mapping of the risks; preventive risk information in Val d'Oise](http://cartelie.application.developpement-durable.gouv.fr/cartelie/voir.do?carte=03151&service=DDT_95) * [simple download (Atom) of the game and associated documents via the internet](http://atom.geo-ide.developpement-durable.gouv.fr/atomArchive/GetResource?id=f0e860af-4f0c-40db-87d4-a3fe13491287&dataType=dataset) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/63528a0c2014656b0c15d1545bde4608fdbc9558)
