Map Viewing Service (WMS) of the dataset: Scopes of the Natural Risk Prevention Plan (PPRN) of Mées — 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.本数据集收录自然风险防范计划（Natural Risk Prevention Plan, NPP）编制全流程各阶段的边界范围。此类边界的共性特征为：系官方正式文书所确立的法定结果，且自指定生效日期起正式生效。 具体涵盖以下三类： — PPRN 指令文件中规定的边界范围； — 与经审批通过的RPP所规制的风险暴露范围相对应的风险暴露范围，此类经审批的边界为公用地役权（utility easement, PM1）； — 与灾害研究覆盖全域相对应的研究范畴。
