Simple download service (Atom) of the dataset: PPRI Seine (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。此类划定区域的核心特征为：系官方行政行为的产物，且自指定日期起生效。具体包含以下三类：
- 由PPR（自然型或技术型）的划定命令所载明的法定划定区域；
- 与经核准的RPP所规制的风险暴露范围相一致的风险暴露范畴；该经核准的划定区域属于公用役地（PPRN对应PM1，PPRT对应PM3）；
- 与危险研究所涉及的覆盖范围相一致的研究范畴。
