Map Viewing Service (WMS) of the dataset: Dax — Landes Natural Risk Prevention Plan (NRPP) Perimeters (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范计划（Natural Risk Prevention Plan，简称NPP）各编制阶段的边界范围。此类边界的核心特征为：系官方行政行为的产物，且自指定生效日期起产生效力。具体包括以下三类： — PPRN指令文书中规定的法定边界； — 与获批RPP所规范的风险暴露范围相一致的风险暴露范畴，该获批边界属于公用役权（PM1）； — 对应灾害研究覆盖范围的研究范畴。
