Dataset Direct Download Service (WFS): Scope of the natural risk prevention plan (PPRN) of the municipality of MERCENAC

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发展阶段划定的各类边界。 边界范围的核心特征为：系法定行为的产物，且自指定日期起产生法律效力。此类边界范围可包含以下类型： — PPR规定指令中载明的法定范围（涵盖自然型与技术型PPR）； — 与经批准的RPP所规制范围对应的风险暴露范围。该经核准的边界范围属于公用役权范畴（PPRN对应PM1，PPRT对应PM3）； — 对应危险源研究覆盖包络的研究范畴。
