Simple download service (Atom) of the dataset: Perimeter of PPRN flooding by overflow of the Charente river of the commune of Tonnay-Boutonne 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.本数据集收录了PPRN在不同开发阶段的边界范围。此类边界的核心特征为：其设立源于法定行政行为，且自指定日期起正式生效。具体包括以下三类： — 自然类PPR审批令中载明的法定划定范围； — 与获批RPP所规制的风险暴露范围相一致的范围，该获批边界属于公用役地（PPRN对应的PM1类型）； — 与风险隐患研究覆盖包络范围相对应的研究范畴。
