Scope of the plan for the prevention of natural hazards (PPRN) of the commune of PAMIERS

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.本数据集收录依据PPRN发展阶段划定的边界范围。 范围边界（perimeter）的核心特征为：其源于正式法定行为，并自指定日期起生效。具体包括以下内容： — PPR（自然类或技术类）法定指令中载明的规定范围； — 对应经批准RPP所规制范围的风险暴露范围。该经核准的范围边界为公用役权（PPRN对应PM1，PPRT对应PM3）； — 对应灾害研究覆盖范畴的研究范围。
