Map Viewing Service (WMS) of the dataset: Scope of the natural risk prevention plan (PPRN) of the municipality of MIREPOIX

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开发阶段划分的管控边界。

管控范围的核心特征为：由官方行政行为所确立，并自指定生效日期起产生法律效力。其涵盖内容如下：
——PPR法定文书中载明的规定范围（涵盖自然属性与技术属性两类）；
——与经批准的RPP所规制的范围相对应的风险暴露范围；该经核准的管控范围属于公用设施地役权范畴（PPRN对应PM1，PPRT对应PM3）；
——对应危险源研究覆盖包络范围的研究范畴。
