Simple download service (Atom) of the dataset: Alum area of the TRTPP TITANOBEL

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.本数据集指代用于RPP风险分析的危险地图（hazard map）中所标注的、暴露于一种或多种危险的区域。 危险地图是危险研究的成果，该研究的目标是评估研究区域内任意点位的各类危险强度。针对不同危险类型，需采用专属的评估方法，由此在研究范围内划定若干区域，形成按危险等级分级的分区体系。对某一特定地域点位分配危险等级时，需综合考量该危险现象的发生概率及其强度等级。 针对PPRT，危险等级需按效应类型逐类在对应地图上确定，并在综合地图上以聚合等级的形式整体呈现。 危险地图中标注的所有危险区域均需纳入本数据集。受防护结构保护的区域也必须予以标注（可采用专属标注方式），因为即便设有防护结构，该区域仍存在遭受危险的可能性（例如结构发生断裂或防护能力不足的情况）。 危险区域可被认定为经开发的数据集，其生成需整合多源的计算、建模或观测所得的危险数据。本数据集类别不涵盖此类源数据，相关源数据应由另一项聚焦危险认知的标准进行规范。 研究区域内的部分区域被视为“无危险或危险可忽略区域”，即经研究确认无危险的区域。此类区域不属于本对象类别的范畴，无需作为危险区域进行标注。
