Dataset Direct Download Service (WFS): 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.

本数据集收录了依据PPRN发展阶段所确定的各类边界。
边界范围的核心特征为：其源自一项官方行政行为，并自指定日期起生效。此类边界范围可包含以下类型：
— PPR（自然类或技术类）批复指令中载明的规定范围；
— 与经批准的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属于公用地役权（PPRN对应PM1，PPRT对应PM3）；
— 与开展危险源研究所覆盖的包络范围相匹配的研究范畴。
