Perimeter of the PPRN AZERGUES

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在不同开发阶段的边界范围。此类边界的核心特征为：系法定行政行为的产物，且自指定日期起生效。具体包括以下三类：
- 由PPR（自然类或技术类）的划定令中列明的法定边界；
- 与经批准的RPP所规制的风险暴露范围相一致的风险暴露边界，此类经批准的边界属于公用地役权范畴（PPRN对应PM1，PPRT对应PM3）；
- 与危险源研究所涉包络范围相一致的研究范畴。
