Simple download service (Atom) of the dataset: Perimeter of the PPR flood of North Arrats and Auroue in the department of Gers

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 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); — scope of study which corresponds to the envelope in which the hazards were studied. This perimeter corresponds to the municipal limit of the municipalities of the PPR.本数据集涵盖PPRN在不同开发阶段的边界范围。此类边界的核心特征为：系经官方行为确立，并自指定日期起产生法律效力，具体包含以下三类： — 自然类或技术类PPR处置指令中载明的法定适用范围； — 经核准的RPP所规制的风险暴露范围，该经核准的边界属于公共地役权（PPRNs对应的PM1）； — 灾害研究覆盖边界，即开展风险灾害研究的范围域。 此类边界与PPR所涉市镇的行政边界相一致。
