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.

总体而言，受险标的（stakes）指受危险源威胁、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。某一评估对象（issue）对危险源的敏感程度，即被称为“脆弱性（vulnerability）”。

本对象类别涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中涉及的全部评估对象。所谓评估对象，即具备明确时间属性的对象，其纳入考量与否取决于RPP的目标，以及其针对所研究危险源的脆弱性。因此，是否纳入RPP评估对象，需根据所针对的危险源类型而定。

上述要素构成了在评估对象分析阶段，研究区域及其周边范围内开展RPP所需的土地覆被认知基础。

本数据集收录的评估对象数据，是风险预防计划编制阶段暴露于危险源中的资产与人员的（figible且非穷尽）现状快照。该数据在RPP获批后不再更新。实际应用中此类数据已不再被直接使用：评估对象会根据实际需求，采用最新数据源重新计算生成。
