Map Viewing Service (WMS) of the dataset: PPRI hazard zone in the catchment area of Girolata and Gradelle — municipality of Osani

Area exposed to one or more hazards represented on the map of hazards used for the risk analysis of PPRI in the catchment area of Girolata and Gradelle in the municipality of Osani.
The hazard map is the result of flood risk studies carried out by BRL in July 1997, supplemented in 2002, and by BCEOM in October 2005.
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.

该区域为奥萨尼（Osani）市镇吉罗拉塔（Girolata）与格拉代勒（Gradelle）汇水区内，用于PPRI风险分析的灾害地图所标注的一种或多种灾害的影响范围。
本灾害地图基于BRL于1997年7月完成的洪水风险研究成果，该研究于2002年得到补充，并由BCEOM于2005年10月进一步完善。
本次评估方法针对不同灾害类型定制，通过划定研究范围内的多个区域，形成基于灾害等级的分级分区体系。为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与强度等级。
本数据集涵盖灾害地图上标注的全部灾害影响区域。即便区域设有防护结构，仍需将其纳入标注（可采用特定标注形式），因为防护结构存在破损或功能不足的风险，此类区域始终被视为处于灾害威胁之下。
灾害区域数据可视为经多源计算、建模或观测得到的灾害数据整合加工后的数据集。本类对象仅涵盖整合后的灾害区域数据，原始源数据的管理与规范由另一项针对灾害认知的标准负责。
