Simple download service (Atom) of the dataset: PPRMT Pontoise (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在开发各阶段的边界范围。此类边界的核心特征为：其设立依据为官方文书，且自指定日期起产生法律效力。具体包含以下三类：
1. 由PPR（自然类或技术类）颁令所载明的法定边界；
2. 与经批准的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设施地役权（PPRN对应PM1，PPRT对应PM3）；
3. 与危险源研究所覆盖的研究包络相对应的研究范围。
