Simple download service (Atom) of the dataset: PPRN-MT of the Massif de l’Hautil (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.

本数据集收录了PPRN开发全周期各阶段的边界范围。此类边界的核心特征为：其设立源于法定行政行为，且自指定日期起正式生效。具体包含以下三类边界：一是PPR指定令中载明的指定边界（适用于自然型或技术型PPR）；二是对应经批准的RPP所规制的风险暴露范围，该核准边界为公用设施地役权（PPRN对应PM1，PPRT对应PM3）；三是危险评估所覆盖的研究范围。
