Dataset Direct Download Service (WFS): 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.

本数据集涵盖PPRN开发各阶段的边界范围。此类边界的核心特征为：均由官方行为设立，并自指定日期起产生法律效力。具体包含以下三类边界：
1. 载于PPR颁令中的规定性边界（PPR分为自然类与技术类）；
2. 与经批准的RPP所规制范围相对应的风险暴露范围，该经批准边界属于公用役权范畴（PPRN对应PM1，PPRT对应PM3）；
3. 与危害研究覆盖包络相对应的研究范围。
