Map Viewing Service (WMS) of the dataset: Perimeter of RIOMOISE AGGLOMERATION PPRNPI(63DDT20140003) approved on 18-07-2016 — Puy-de-Dôme

This dataset contains the boundaries at the different stages of the 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 specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖了PPRN各发展阶段的边界范围。此类边界的核心特征为：其设立依据法定行为，且自指定日期起产生法律效力。具体如下： — 天然或技术类PPR指令文件中载明的规定范围； — 与获批RPP所规制范围相对应的风险暴露范围。该获批边界属于公用设施地役权，其中PPRN对应PM1、PPRT对应PM3； — 危险源研究覆盖范畴对应的研究范围。
