Dataset Direct Download Service (WFS): Perimeter of the PPRN of the municipality of Marsilly (Boundary rivers — coastal erosion and marine submersion)

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.本数据集收录了PPRN开发各阶段的边界范围。此类边界的核心特征为：系官方行为的产物，且自指定日期起生效，具体如下： — 自然属性PPR处方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；该经核准的边界属于公共事业地役权（PPRN对应的PM1）； — 对应危险性研究覆盖范畴的研究范围。
