Map Viewing Service (WMS) of the dataset: Perimeter of PPRN (PPRI de la Risle) in the department of Orne

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。此类边界范围的核心特征为：系官方行为所产生的法定结果，且自指定日期起生效。具体包含以下三类范畴：一是由PPR（自然型或技术型）的划定令所载明的法定边界范围；二是与经核准的RPP所规制的风险暴露范围相符的风险暴露范畴，该经核准的边界范围属于公用役权范畴（PPRN对应PM1，PPRT对应PM3）；三是与危险研究所覆盖的研究范围相一致的研究范畴。
