Simple download service (Atom) of the dataset: Perimeter of the PPRi Loire Valley, Val d’Ardoux

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 following:
— prescribed scope contained in the prescription order of a PPR (natural or technological);
— scope of risk exposure 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 which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRN开发各阶段的边界数据。此类边界的核心特征为：由官方行为依法设立，并自指定生效日期起产生法律效力。具体包括以下三类：
— PPR（自然类或技术类）审批文书中载明的法定适用范围；
— 对应经批准RPP所规制范围的风险暴露范围。该核准边界为公用役权，其中PPRN对应PM1，PPRT对应PM3；
— 研究范围：即开展风险隐患研究所覆盖的包络范围。
