Simple download service (Atom) of the dataset: Synthexim interor PPRT hazard zone

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 assignment 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 by effect effect on maps by type of effect and overall on an aggregated level on a synthesis map.All hazard areas represented on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered to be subject to hazard (cases of breakage or inadequacy of the structure).The hazard zones may be classified as data compiled in so far as they result from a synthesis using several sources of calculated, modelled or observed hazard data. These source data are not covered by this class of objects but by another standard dealing with the knowledge of hazards.Some areas of the study perimeter are considered “zero 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.

本数据集涵盖用于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。该灾害地图是灾害研究的成果，其核心目标为评估研究区域内任意点位的各类灾害强度。针对不同灾害类型需采用专属评估方法，据此在研究范围内划定若干区域，形成按灾害等级分级的分区结果。对研究区域内指定点位的灾害等级进行赋值时，需综合考量该危险现象的发生概率及其强度等级。针对PPRT，其灾害等级需按效应类型在专项地图上确定，并在综合地图上以聚合后的总体等级形式呈现。灾害地图上标注的所有灾害影响区域均需纳入本数据集。受防护结构保护的区域也必须标注（可采用专属标注方式），因为即便设置了防护结构，仍存在结构失效或防护不足的可能，此类区域始终被视为处于灾害影响范围内。当灾害区域数据是通过整合多源计算、建模或观测得到的灾害数据合成而来时，可对其进行分类归档。此类源数据不属于本对象类别的覆盖范围，而是由另一项针对灾害认知的标准进行规范。研究范围内的部分区域被划为"零灾害或可忽略灾害区域"，即经研究确认无灾害风险的区域。此类区域不属于本对象类别的覆盖范围，无需作为灾害影响区域进行标注。
