Simple download service (Atom) of the dataset: PPRI Presles (Perimeter)

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.本数据集涵盖PPRN发展各阶段的边界。此类边界的核心特征为：其设立依据官方公文作出，且自指定日期起产生法律效力。具体包括： 1. 依据PPR（天然型或技术型）制定令所载明的法定边界； 2. 与经核准的RPP所规制的风险暴露范围相一致的范围，该核准边界属于公用地役权（PPRN对应PM1，PPRT对应PM3）； 3. 与危险研究所覆盖的范围相一致的研究范围。
