Plan for the prevention of natural hazards of field movement — Commune de Sauveterre — Area of hazard — Department of Tarn-et-Garonne

Area exposed to one or more hazards shown on the hazard map used for PPR risk analysis. The map d'random is the result of the study of hazards whose goal is to evaluate the intensity of each hazard at any point in the zone of study. The evaluation method is specific to each type of hazard. It leads to the delimitation of a set of zones on the perimeter d'study constituting a graduated zoning according to the level of l'aira. L' attribution of Â#x27;A level of #x27; hazard at a given point in the territory takes into account the probability of #x27; occurrence of the dangerous phenomenon and its degree of Â#x27; intensity. For multi-random PPRNs, each zone is usually spotted on the d'aira map by a code for each hazard to which it is exposed. All hazard zones shown on the hazard map are included. Areas protected by protective works must be represented (possibly specifically) because they are always considered subject to the hazard (case of rupture or d' inadequacy of the work). Hazard zones can be described as elaborated data as they result from a synthesis using several calculated, modelled or observed data sources. These source data are not affected by this class of objects but by another standard dealing with the knowledge of hazards. Some areas of the perimeter of the study are considered “zero or insignificant hazard zones”. It is the areas where the hazard has been studied and is zero. These zones are not included in class d'objects and n'are not to be represented as zones d'aira. However, in the case of natural PPRs, regulatory zoning may classify certain areas not exposed to the hazard zone as a prescribing zone (see ZonePPR class definition). __Origin__ Three genealogies are possible to obtain the series of data constituting a PPR:* L' elaboration of the PPR has taken place a posteriori of the publication of this standard. The master of the PPR was able to take into account the technical specifications of the PPR standard from the start of the procedure.* L' preparation of the PPR and the publication of this standard are concurrent. The geographical data had to be the subject of a “hot” standardisation during the procedure, taking advantage of the knowledge of all stakeholders in the file.* The publication of the standard took place after the adoption of the PPR procedure. 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 a 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. __Partner organisations__ DDT Tarn-et-Garonne, DDTM Pas-de-Calais __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-46265bb0-25e5-4fb9-ba50-b1a2fe43961f) * [COVADIS data standard: Table containing all restricted zones of a PPRN.](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_P) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/5b3cca207336cc5ddca3679ec63f979c9d049ea1)
