Simple download service (Atom) of the dataset: Perimeter of the PPRN Saumur Coteau (Saumur)

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PPRN开发各阶段的边界范围。此类边界的核心特征为：均由官方行为生成，并自指定日期起生效，具体如下：
——PPR（天然或技术类）相关行政裁定令中载明的规定适用范围；
——经核准RPP所规制的风险暴露范围，该核准边界为公用设施地役权（utility easement），PPRN对应PM1，PPRT对应PM3；
——研究范围，即开展危险研究的包络范围。
