Simple download service (Atom) of the dataset: RPRI hazard zone in the Vetricella catchment area

Area exposed to one or more hazards represented on the hazard map used for risk analysis of RIP in the Vetricella watershed.
The hazard map is the result of a flood risk study conducted by BRL Engineering in July 1997, which produced the first PPRI in the Vetricella watershed approved on 23/09/2003.
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.
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.

本数据集对应维特里切拉（Vetricella）流域内用于RIP风险分析的灾害地图（hazard map）所标注的一种或多种灾害影响区域。
该灾害地图源自BRL工程（BRL Engineering）于1997年7月开展的洪水风险研究，该研究编制了维特里切拉流域首份于2003年9月23日获批的PPRI。
评估方法针对各类灾害定制专属方案，可在研究范围内划定若干区域，并依据灾害等级完成分级分区。针对某一特定地域点位的灾害等级赋值时，需综合考量该危险现象的发生概率及其强度量级。
本数据集涵盖灾害地图中标注的全部灾害影响区域。对于受防护结构保护的区域，亦需以特定方式（若有必要）予以呈现，因此类区域仍存在受灾害影响的风险（如结构溃决或防护效能不足的情形）。
灾害区域可被归类为整合加工数据，其生成依托多源经计算、建模或观测得到的灾害数据。此类源数据不属于本类对象的范畴，而是由另一项专门研究灾害认知的标准规范所覆盖。
