Map Viewing Service (WMS) of the dataset: Perimeter of PPRN flooding by overflow of the Charente River in the municipality of Geay 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PPRN开发各阶段的边界范围。此类边界范围的核心特征为：均由官方法令确立，并自指定日期起产生法律效力，具体如下： — 自然类PPR处方令所载明的规定范围； — 与获批RPP规制范围相一致的风险暴露范围。 该获批边界范围属于适用于PPRN的PM1的地役权（utility easement）；— 与风险隐患研究覆盖范围相对应的研究范围。
