Dataset Direct Download Service (WFS): Perimeter of the PPRi de la Loire val d’Orléans (Orlean city)

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开发各阶段的边界范围。此类边界的核心特征为：其效力源于官方法定行政行为，并自指定日期起生效。
具体涵盖以下三类边界：
— PPR（自然类或技术类）规制指令中载明的法定适用范围；
— 与获批RPP所规制范围相对应的风险暴露范围，该获批边界为公用役地权（PPRN对应PM1，PPRT对应PM3）；
— 对应危险源研究空间覆盖范围的研究边界。
