Simple download service (Atom) 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.

本数据集涵盖了自然风险防治计划（Natural Risk Prevention Plan, NPP）各发展阶段的边界范围。此类边界的特征为：均由官方正式文件确立，并自指定日期起生效。具体如下：
— PPRN指令中规定的法定边界；
— 对应经核准的RPP所规制的风险暴露范围，该核准边界为公用设施地役权（PM1）；
— 对应灾害研究覆盖范围的研究边界。
