Map Viewing Service (WMS) of the dataset: Zone of hazard Movement of terrain — municipality of PILA-CANALE

Area exposed to one or more hazards represented on the map of the rough terrain movement.
The hazard map is the result of the hazard study carried out by the CETE in December 2010, whose objective is to identify the rockfall hazard south-east of the village of PILA CANALE to permmetre a PLU orientation aimed at integrating natural risk.
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.
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.

本数据集涵盖崎岖地形运动灾害图中标记的一处或多处受灾害（hazard）影响的区域。
该灾害图由CETE于2010年12月开展的灾害研究成果编制而成，其旨在识别皮拉卡纳莱（PILA CANALE）村东南部的落石灾害（rockfall hazard），以支撑旨在整合自然风险的地方城市规划（PLU，Plan Local d'Urbanisme）制定工作。
本评估方法针对不同灾害类型量身定制，通过对研究范围内的区域进行划定，形成按灾害等级分级的分区方案。针对研究区域内特定点位的灾害等级赋值，需综合考量该危险现象的发生概率及其强度等级。
灾害图中标记的所有灾害影响区域均已纳入本数据集。受防护结构保护的区域亦需标注（可采用专属标识方式），因为即便设有防护结构，仍存在结构破损或防护不足的可能，此类区域仍被视为处于灾害风险之中。
灾害分区数据可视为经过开发的数据集：其基于对多源计算、建模或观测所得的灾害数据进行综合整合而成。本数据集仅涵盖灾害分区成果，原始源数据的相关内容不属于本数据集范畴，需遵循另一项针对灾害认知的标准规范。
研究范围内的部分区域被划定为“无灾害或灾害可忽略区域”，即经专项研究确认不存在灾害风险的区域。
