Map Viewing Service (WMS) of the dataset: Scopes of the Oeyregave Natural Risk Prevention Plan (NPP) — 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.

本数据集收录了自然风险防范计划（Natural Risk Prevention Plan, NPP）编制各阶段的边界范围。此类边界范围的核心特征为：均由官方法定行为衍生而来，且自指定生效日期起具备法律效力。

具体涵盖以下三类边界：
— PPRN法定指令文书中载明的划定边界；
— 与经核准的RPP规制范围一致的风险暴露范围，该核准边界属于公用役权（utility easement）范畴，编号为PM1；
— 对应灾害隐患研究覆盖包络范围的研究范畴。
