Dataset Direct Download Service (WFS): Hazard zone of the Technology Risk Prevention Plan (PPRT) BOREALIS PEC RHODIA BUTACHIMIE in the Haut-Rhin

Area exposed to one or more hazards represented on the hazard map used for risk analysis of the RPP.
The hazard map is the result of the study of hazards, the objective of which is to assess the intensity of each hazard at any point in the study area. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity.
For PPRTs the hazard levels are determined effect by effect on maps by type of effect and overall on an aggregated level on a synthesis map.

All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure).
Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards.
Some areas within the study area are considered “no or insignificant hazard zones”. These are the areas where the hazard has been studied and is nil. These areas are not included in the object class and do not have to be represented as hazard zones.

本类对象指用于RPP风险分析的灾害地图（hazard map）上标注的、受一种或多种灾害影响的区域。
灾害地图是灾害研究的成果，该研究旨在评估研究区域内任意点位的各类灾害强度。评估方法因灾害类型而异，最终将在研究范围内划定一系列区域，形成按灾害等级分级的区划。对研究区域内任意点位分配灾害等级时，需综合考量该危险现象的发生概率及其强度等级。针对PPRTs，灾害等级需按效应类型在对应地图上逐一确定，并在综合地图上按聚合层级完成整体判定。
灾害地图上标注的所有灾害影响区域均需纳入本类对象。受防护结构保护的区域亦须以特定方式标注（可采用专属形式），因为即便设有防护结构，仍存在结构破损或失效的可能，此类区域依旧被视为处于灾害风险之中。
灾害区域可被视为经开发的数据集，其生成依托多源计算、建模或观测获取的灾害数据进行综合整合。本类对象不涉及上述源数据，相关源数据的管理应遵循另一项聚焦灾害认知的标准。
研究区域内部分区域被划为"无灾害或灾害可忽略区域"，即经研究确认灾害风险为零的区域。此类区域不属于本类对象范畴，无需作为灾害区域进行标注。
