Dataset Direct Download Service (WFS): Perimeter of the PPRi Essonne _ Loiret

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 following:
— prescribed scope contained in the prescription order of a PPR (natural or technological);
— scope of risk exposure 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 which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRN在各开发阶段的边界范围。此类边界的核心特征为：其产生于官方行为，并自指定日期起生效。具体如下：
— 纳入PPR（自然类或技术类）处置令的规定适用范围；
— 与经核准的RPP所规制范围相匹配的风险暴露范围。该经核准的边界属于公用役地范畴（PPRN对应PM1，PPRT对应PM3）；
— 对应风险研究覆盖范围的研究范畴。
