Dataset Direct Download Service (WFS): Perimeters of the Vienna flood risk prevention plan (PPRI) — municipality of Châtellerault in Vienna

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 and PM3 for PPRTs);
— scope of study which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRN在各开发阶段的边界范围。此类边界的核心特征为：其生成源于法定行为，并自指定日期起生效。具体包括以下三类：
— 天然类与人工类PPR处置令所载明的法定适用范围；
— 与获批RPP规制范围相对应的风险暴露范围。该获批边界属于公用役地，其中PPRN对应PM1，PPRT对应PM3；
— 对应危险源研究覆盖包络的研究范畴。
