Dataset Direct Download Service (WFS): Specific issues taken into account in the PPRN flooding of the Charente River in the commune of St-Sever-de-Saintonge 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.一般而言，风险受体指受灾害威胁、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。某一研究对象对灾害的敏感程度即被称为“脆弱性（vulnerability）”。 该对象类别涵盖了风险预防计划（RPP）研究中涉及的全部研究对象。此处的“研究对象”为带有时效性的实体，其是否纳入考量取决于风险预防计划的目标，以及其对所研究灾害的脆弱性。因此，PPR研究对象是否纳入分析，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，上述要素构成了研究区域及其周边区域风险预防计划编制所需的土地覆被相关认知基础。 该研究对象数据集呈现了风险预防计划编制阶段，暴露于各类灾害中的资产与个体的（可表征且非穷尽的）现状快照。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直接使用：研究对象会根据实际需求，结合最新数据源重新计算生成。
