Dataset Direct Download Service (WFS): Perimeter of PPRN on the department of Meuse (55)

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（PPRN）发展各阶段的边界信息。此类边界的核心特征为：其生成源于官方行政行为，并自指定日期起正式生效，具体分类如下：
— 纳入PPR（PPR，含自然型与技术型）规定指令中的法定范围；
— 与经审批的RPP（RPP）所规制范围相对应的风险暴露范围。该经审批的边界属于公用役权，其中PPRN对应PM1，PPRT对应PM3；
— 研究范围，即针对各类危害开展研究时所覆盖的包络范围。
