PPRI: Areas exposed to hazards of IPPs — Isère

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 flood PPRs, each zone is usually spotted on the map d'a 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 flood PPRs, regulatory zoning may classify certain areas not exposed to hazard as a prescription zone. __Origin__ This dataset is in line with the regional standard and not that of COVADIS. It constitutes the aggregation of all the digitised hazard zones at the scale of the Scan or the Cadastre The boundaries of a zone d’#x27;aira are represented on the map of hazards according to the level of l'random. In other words, polygon objects representing zones d'random form a partial coverage of the studied area of which each cover element is a closed polygon in which hazards have the same level of ' intensity. In other words, the criterion for cutting the zones d'random is the level of l'random. Source of georeferencing according to the municipality: Scan25 (number and year different according to the PPRN) or Cadastre DDFIP (year different according to the PPRN). __Partner organisations__ DDT Isère [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/1722c2537dec47df6016a171d6d6a0bf4e64ce65)
