Map Viewing Service (WMS) of the dataset: Perimeters of the Tercis-les-Bains 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.

本数据集收录自然风险防范计划（Natural Risk Prevention Plan, NPP）各制定阶段的边界范围。此类边界的共性特征为：均由官方法定文书确立，且自指定日期起生效。
具体包含以下三类边界：
— PPRN审批指令中规定的法定边界；
— 与经核准的RPP所规制的风险暴露范围相对应的边界，该核准边界为公用役地（utility easement, PM1）；
— 对应灾害风险研究覆盖范围的研究边界，亦即开展隐患研判的全域范围。
