Dataset Direct Download Service (WFS): Perimeter of PPRN flooding by overflow of the median sector the Boutonne of the municipality of Antezant-la-Chapelle

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在各发展阶段的边界范围。此类边界的共性为：均由官方行为所设立，且自指定日期起生效。具体分类如下： —— 自然类PPR行政许可令中载明的法定范围； —— 风险暴露范围，与经批准的RPP所规制的范围相对应。该经核准的边界为公用役权（PPRN对应PM1）； —— 研究范围，即开展危害研究的包络区域。
