Map Viewing Service (WMS) of the dataset: Perimeter of the PPRN forest fires, erosion and marine submersion of the peninsula of Arvert in the commune of La Tremblade in Charente-Maritime

This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖公共项目审查网络（PPRN）开发各阶段的边界范围。此类边界的核心特征为：均由官方公务行为所确立，并自指定生效日期起产生法律效力。具体包含以下几类边界： —— 自然类公共项目规划（PPR）法定指令中载明的法定划定范围； —— 与已核准的风险规划报告（RPP）所规制范围相对应的风险暴露范围； 该类已核准边界属于公用设施地役权（PPRN项下PM1类型）； —— 对应隐患研究覆盖范围的研究划定边界。
