Dataset Direct Download Service (WFS): Perimeters of the Peyrehorade Natural Risk Prevention Plan (PPRN) — Landes (40)

This dataset contains the boundaries at the various stages of the development of the Natural Risk Prevention Plan (NPP). 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 perimeter in the prescription order of a PPRN;
— scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1);
— scope of study which corresponds to the envelope in which the hazards were studied.

本数据集涵盖自然风险防控计划（Natural Risk Prevention Plan, NPP）编制各阶段的边界范围。此类边界的核心特征为：均由官方正式文书确立，并自指定日期起生效。

具体包括以下三类：
— PPRN指令文书中载明的法定边界范围；
— 与已获批RPP所规制的风险暴露范围相一致的风险暴露边界，该获批边界属于公用役权（PM1）；
— 对应风险隐患研究覆盖范围的研究边界。
