Map Viewing Service (WMS) of the dataset: Scope of the plan for the prevention of natural hazards (PPRN) of the municipality of Verniolle

This dataset contains the boundaries according to the stage of development of the PPRN.
The characteristic of a perimeter is to be the consequence of an official act and to produce its effects from a specified date. This may include:
— 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.

本数据集包含依据PPRN开发阶段划定的边界范围。
边界范围的核心特征为：系官方行政行为的产物，且自指定日期起产生法律效力。此类边界范围可涵盖以下情形：
— 自然类或技术类PPR的命令文书中载明的规定范围；
— 与经核准的RPP所规制范围相对应的风险暴露范围。该经核准的边界范围为公用役权（PPRN对应PM1，PPRT对应PM3）；
— 对应开展风险研判所覆盖包络范围的研究范围。
