Map Viewing Service (WMS) of the dataset: Specific issues taken into account in the PPRN flooding of the river Charente in the commune of Gonds in Charente-Maritime

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.概言之，承灾体（stakes）指的是受灾害（hazard）威胁、且有可能因之遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象针对灾害的敏感程度被称为“脆弱性（vulnerability）”。 该对象类涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中所涉及的全部研究对象。此处的“研究对象”为带有明确时间属性的实体，其是否被纳入评估范畴，取决于该风险预防计划的研究目标，以及其针对所研究灾害的脆弱性。因此，PPR研究对象是否被纳入评估，需根据所针对的灾害类型而定。 在开展研究对象分析的阶段，上述要素构成了在研究区域及邻近区域开展风险预防计划编制所需的土地覆被（land cover）认知基础。 该研究对象数据呈现了风险预防计划编制阶段，暴露于灾害中的承灾资产与人员的有限且非穷尽快照。该数据在风险预防计划获批后不再更新。实际应用中该数据已不再被使用：研究对象会根据需求，依托最新数据源重新计算生成。
