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 or near the study area, at the time of the analysis of the issues. The data on issues represent a (figible and non-exhaustive) photograph of assets and individuals 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，受险标的指受某一灾害威胁，并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一风险点针对灾害的敏感程度，被称为「易损性（Vulnerability）」。本对象类别涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部风险点。风险点是具备明确时间属性的对象，其相关考量维度取决于风险预防计划（RPP）的目标，以及该风险点针对所研究灾害的易损性。因此，是否纳入某RPP风险点，需结合当前所应对的灾害类型而定。在开展风险点分析阶段，上述要素构成了研究区域及其周边区域风险预防计划编制所需的土地覆盖认知基础。该风险点数据呈现的是风险预防计划编制阶段，受灾害威胁的资产与人群的（具象化且非穷尽）快照。该数据在风险预防计划获批后不再更新，实际应用中亦不再直接复用：需根据实际需求结合最新数据源重新计算风险点相关信息。
