Map Viewing Service (WMS) of the dataset: Technological Risk Prevention Plan (PPRT) hazard zone DSM RUBIS in 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.

用于RPP风险分析的灾害地图（hazard map）上标注的、受到一种或多种灾害影响的区域。
该灾害地图是灾害研究的成果，其研究目标为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，会在研究边界范围内划定若干区域，形成按灾害等级分级的区划。针对研究区域内的给定点位确定灾害等级时，需综合考量危险现象的发生概率及其强度程度。
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等级进行整体判定。
灾害地图上标注的所有灾害区域均需纳入本数据集的对象范畴。受防护结构保护的区域也必须进行标注（可采用专属标识形式），因为此类区域始终会被视为处于灾害威胁之下，例如结构破损或防护不足的场景。
灾害区域可作为衍生数据进行描述，此类数据源自对多源计算、建模或观测得到的灾害数据的综合分析。上述源数据不属于此类对象范畴，而归属于另一项专门研究灾害认知的标准规范。
研究区域内的部分区域被认定为"无灾害或灾害可忽略区域"，即经研究确认灾害影响为零的区域。此类区域无需纳入本对象类，也无需作为灾害区域进行标注。
