PPRN Regulatory Zoning (PPR Montagne de Savoie)

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:- prescribed perimeter set out in the Prescribing Order of a PPR (natural or technological);- scope of exposure to risks 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 that corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN在开发各阶段的边界范围。此类边界的核心特征为：其生成源自法定行政行为，并自指定生效日期起产生法律效力。具体包含以下三类边界： - 由PPR规定令划定的法定边界（涵盖自然属性与技术属性两类）； - 风险暴露范围，该范围与经核准的RPP所规制的范畴相一致。该经核准的边界属于公用设施地役权（PPRN对应PM1，PPRT对应PM3）； - 研究范畴，即开展危害研究时所覆盖的包络范围。
