Simple download service (Atom) of the dataset: PPRMT Soisy-sous-Montmorency (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（PPRN）不同开发阶段的边界范围。此类边界的核心特征为：系官方行政行为的产物，且自指定日期起产生法律效力。具体包含以下三类边界：
—— 法定划定边界：自然或技术型PPR（PPR）的划定令（Prescribing Order）中载明的范围；
—— 风险暴露范围：与经批准的RPP（RPP）所规制的范围相一致；该经批准的边界属于公用设施地役权（utility easement），其中PPRN对应PM1，PPRT对应PM3；
—— 研究范围：与开展危害研究所覆盖的包络范围一致。
