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

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.

本数据集收录了与PPRN发展阶段相对应的各类边界范围。此类范围的核心特征为：由官方行为所确立，并自指定生效日期起产生法律效力。其涵盖范畴如下：——PPR（自然类或技术类）的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。该经核准的范围属于公共役权（PPRN对应PM1，PPRT对应PM3）；——对应危险源研究覆盖范畴的研究范围。
