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

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周边保护与限制网络（Perimeter Protection and Restriction Network，缩写PPRN）发展阶段划分的管控边界。
管控边界的核心特征为：其源于官方行政行为，并自指定日期起产生法律效力。此类边界可涵盖以下类型：
— 由PPR（Protection and Restriction Prescription，含自然类与技术类）管控指令中载明的法定范围；
— 与获批RPP（Regulated Protection and Restriction Prescription）所规制的风险暴露范围一致的范围；该获批管控边界属于公用役地（PPRN对应PM1，PPRT对应PM3）；
— 对应危险源研究覆盖范围的研究范畴。
