Map Viewing Service (WMS) of the dataset: Perimeter of PPRN on the department of Meuse (55)

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在各开发阶段的边界范围。此类边界的核心特征为：其源于官方法定程序，且自指定日期起生效，具体包含以下三类：
— PPR（自然类或技术类）指令文书中载明的法定范围；
— 与经核准RPP所规制范围相对应的风险暴露范围：该核准边界属于公用地役权（PPRN对应PM1，PPRT对应PM3）；
— 对应灾害研究覆盖范围的研究边界。
