The BIMA Technology Risk Prevention Plan (PPRT) in Haut-Rhin

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，受险对象（stakes）指受灾害（hazard）威胁、并可能因此遭受影响或损毁的人员、财产、各类活动、文化遗产及环境遗产要素。某一对象对灾害的易感程度被称为“脆弱性（vulnerability）”。
本对象类别涵盖了风险预防计划（Risk Prevention Plan，以下简称RPP）研究中涉及的全部风险点。风险点是一类带时间戳的对象，其是否被纳入评估范围取决于RPP的目标，以及其在所研究灾害下的脆弱性。因此，某一PPR风险点是否会被纳入评估，需根据所针对的灾害类型而定。
在开展风险点分析的阶段，上述要素构成了研究区域及其周边范围内，制定RPP所需的土地覆被（land cover）相关认知基础。
风险点数据呈现的是风险预防计划制定时，受灾害威胁的资产与人员的（兼具灵活性与非全面性的）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直接复用，而是根据实际需求结合最新数据源重新计算相关风险点。
