Dataset Direct Download Service (WFS): Scope of the Natural Risk Prevention Plan (PPRN) of the Mimizan — Landes sector (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治计划（Natural Risk Prevention Plan, NPP）全流程编制阶段的各类边界范围。此类边界的共性特征为：均由官方法定文书确立，且自指定生效日期起产生法律效力。具体包括以下三类：
—— PPRN审批令中载明的划定边界；
—— 与获批RPP所规制的风险暴露范围相一致的风险暴露边界，此类获批边界属于公共用地役权（utility easement, PM1）；
—— 对应灾害研究覆盖范围的研究边界。
