Simple download service (Atom) of the dataset: Linear stake of PPRN flooding by overflow of the Charente river of the commune of Chérac

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，承险体（stakes）指受灾害威胁、且可能因灾害遭受影响或破坏的人员、财产、活动、文化或环境遗产要素。评估对象（issue）对灾害的敏感程度被称为“脆弱性（vulnerability）”。
该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。评估对象是带有时间标注的实体，其是否被纳入考量取决于RPP的目标以及其针对所研究灾害的脆弱性。因此，PPR评估对象是否会被纳入评估，需结合当前应对的灾害类型而定。
在开展评估对象分析阶段，上述要素构成了研究区域及其周边区域内，制定RPP所需的土地覆被认知基础。
该评估对象相关数据呈现了风险预防计划制定阶段，受灾害影响的资产与人群的（可直观呈现且非穷尽的）快照式记录。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：需结合最新数据源，按需重新计算评估对象相关信息。
