Map Viewing Service (WMS) of the dataset: Specific issues taken into account in the PPRN flooding of the river Charente of the municipality of Taillebourg 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，承险体指受某一灾害威胁、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。某一对象针对某类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议题。评估议题是一类带时间戳的对象，其是否被纳入考量取决于RPP的目标，以及该议题针对所研究灾害的脆弱性。因此，PPR评估议题是否被纳入考量，取决于当前所针对的灾害类型。 在开展评估议题分析的阶段，上述要素构成了研究区域及其周边区域内，风险预防计划编制所需的土地覆盖相关知识基础。 评估议题相关数据，呈现了风险预防计划编制阶段内，暴露于各类灾害中的资产与人员的一幅（虽可具象化但非穷尽的）快照。该数据在风险预防计划获批后不再更新。实际应用中此类数据已不再被使用：评估议题将根据实际需求，使用最新数据源重新计算得出。
