PPRI Sausseron (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发展不同阶段的边界范围。此类边界的核心属性为：由法定行为所创设，并自指定日期起产生法律效力。具体包含以下三类范畴：
1. 由PPR指定令所载明的法定边界（涵盖自然型与技术型PPR）；
2. 与经批准的RPP所规制的风险暴露范围相匹配的风险暴露范畴，该经批准的边界属于公用地役权（PPRN对应PM1，PPRT对应PM3）；
3. 与危险源研究覆盖范围相一致的研究范畴。
