Simple download service (Atom) of the dataset: Perimeter of the PPRi de la Loire val d’Orléans (upstream)

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.

本数据集涵盖了PPRN在不同开发阶段的边界范围。此类边界的核心特征为：其生成源于官方行为，且自指定日期起产生法律效力。

具体涵盖如下三类边界：
— 由PPR（天然或技术类）的审批令所规定的适用范围；
— 与经批准的RPP所规制的范围相对应的风险暴露范围。该经核准的边界为地役权（PPRN对应PM1，PPRT对应PM3）；
— 研究范围，即开展危害研究的包络范围。
