Map Viewing Service (WMS) of the dataset: Scope of the plan for the prevention of natural hazards (PPRN) of the municipality of DURBAN-SUR-ARISE

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发展阶段相对应的边界范围。 管控范围的核心特征为：由官方审批行为所确立，并自指定生效日期起产生效力。其涵盖范畴包括： — 载于PPR（含自然类与技术类）审批令（prescription order）中的规定管控范围； — 与经审批RPP所规制的范围相对应的风险暴露范围（risk exposure）。该经审批的管控范围属于公共役权（utility easement），PPRN对应PM1，PPRT对应PM3； — 对应危险源（hazards）研究覆盖范围的研究范畴。
