Dataset Direct Download Service (WFS): Specific issues taken into account in the PPRN flooding of the river Charente of the commune of La Vallée 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，受险对象包括人员、财产、各类活动以及文化或环境遗产要素，它们正遭受灾害威胁，并有可能因此受到影响或损毁。某一对象针对灾害的敏感性被称为脆弱性（vulnerability）。 此对象类别涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部受险对象。受险对象为带有时间戳的对象，其是否被纳入考量取决于风险预防计划的目标，以及该对象针对所研究灾害的脆弱性。因此，是否纳入某一RPP受险对象，需结合当前应对的灾害类型而定。 在开展受险对象分析时，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认知基础。 该受险对象数据，是风险预防计划编制阶段内暴露于灾害中的资产与人员的（具象且非穷尽的）快照式记录。该数据集在风险预防计划获批后不再进行更新。实际应用中该类数据已不再直接复用，需根据实际需求依托最新数据源重新计算受险对象相关信息。
