Simple download service (Atom) of the dataset: Linear stake of a PPRT from Mesnil Saint Nicaise and Nesle

Generally speaking, the stakes are people, property, activities, cultural or environmental heritage elements, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability.”This object class brings together all the issues that have been addressed in the RPP study. An issue is a dated object whose consideration depends on the purpose of the RPP and its vulnerability to the hazards studied. A PPR issue can therefore be considered (or not) depending on the type or types of hazard being addressed. These elements form the basis of knowledge of the land cover necessary for the development of the RPP, in the study area or near it, at the time of the analysis of the issues. The data on the issues represent a photograph (figential and not exhaustive) of the property and of the people exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the issues are recalculated as necessary with up-to-date data sources.一般而言，风险标的系指受灾害威胁且可能遭受其影响或损害的人员、财产、活动、文化或环境遗产要素。某风险议题对灾害的敏感性被称为“脆弱性（vulnerability）”。本对象类别涵盖了风险预防计划（Risk Prevention Plan，缩写RPP）研究中涉及的全部风险议题。所谓风险议题，系指具有明确时间属性的对象，其是否纳入考量取决于RPP的研究目的，以及其对所研究灾害的脆弱性。因此，是否需考虑某RPP风险议题，取决于当前所应对的灾害类型。在对风险议题开展分析时，上述要素构成了研究区域及其周边区域编制RPP所需的土地覆盖认知基础。该风险议题数据，在RPP编制阶段，呈现了受灾害影响的财产与人员的快照（仅为示例且非穷尽）。该数据在RPP获批后不再更新。实际应用中，此类数据已不再使用：研究人员可根据需要，借助最新数据源重新计算风险议题。
