Dataset Direct Download Service (WFS): Perimeter of the FNIPP of the mancelle agglomeration

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）发展不同阶段的边界范围。此类边界的本质特征为：系官方行为的法定产物，且自指定日期起生效。具体包含以下三类：
其一为PPR（PPR）规定令中载明的法定边界（涵盖自然类与技术类PPR）；
其二为与经批准的RPP（RPP）所规制范围相对应的风险暴露范围。该经批准的边界属于公用役权范畴（PPRN对应PM1，PPRT（PPRT）对应PM3）；
其三为与危险源研究覆盖包络相对应的研究范围。
