Simple download service (Atom) of the dataset: Perimeter of PPRN (PPRI de l’Orne Amont) 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（PPRN）发展不同阶段的边界信息。此类边界的核心特征为：其源自法定行为，并自指定日期起产生法律效力。具体包含以下三类：
1. 载于PPR（PPR）规定令中的规定性边界，涵盖自然类或技术类PPR；
2. 与经批准的RPP（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共役权范畴，其中PPRN对应PM1（PM1），PPRT对应PM3（PM3）；
3. 对应于危害研究覆盖范围的研究范围。
