Dataset Direct Download Service (WFS): Perimeter of PPRN flooding by overflow of the Seugne and land movements of the commune of Jonzac 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。此类边界的核心特征为：系官方行为所产生的结果，且自指定日期起产生法律效力。具体包括以下三类：
— 自然PPR的指令书中所载的规定范围；
— 对应经批准RPP所规制范围的风险暴露范围；该经核准的边界为公用役权（PPRN的PM1项）；
— 与危险源研究覆盖包络范围相对应的研究范畴。
