Map Viewing Service (WMS) of the dataset: PPR USTARITZ (64DDTM20160012) — Perimeter of the Ustaritz Flood Risk Prevention Plan (PPRN-PPRI) (64547), Pyrenees-Atlantiques department

This dataset contains the boundaries at the different stages of the development of the PPRN. 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 scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied. Table of perimeters identified during the study of a PPR. This table contains as a minimum the prescribed perimeters for RPPs in the prescribed state and the prescribed and risk exposure perimeters for approved RPPs.本数据集收录了PPRN（原文未标注全称）全发展周期各阶段的边界范围。此类边界的共性特征为：均由法定文书正式确立，且自指定生效日期起正式生效，具体包含以下三类范围： — 载于PPR（原文未标注全称）指令文书中的规定范围，涵盖自然类与技术类PPR； — 对应获批RPP（原文未标注全称）所规制范围的风险暴露范围。该获批边界属于公用役权（utility easement）范畴，其中PPRN对应PM1，PPRT对应PM3； — 与风险隐患研究覆盖包络范围相对应的研究范围。 PPR研究过程中确定的边界范围表。该表至少包含处于规定状态的RPP的规定边界，以及获批RPP的规定边界与风险暴露边界。
