Dataset Direct Download Service (WFS): Surface issues taken into account in the PPRN flooding of the river Charente of the commune of Chaniers en 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，承灾体指受到灾害威胁、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。某一对象针对灾害的敏感程度被称为“易损性”。
本对象类涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中涉及的全部研究对象。所谓研究对象，即带有时间戳的对象，其是否被纳入考量取决于该风险预防计划的目标，以及其针对所研究灾害的易损性。因此，某一RPP研究对象是否被纳入评估，需结合当前所针对的灾害类型而定。
上述要素构成了在研究对象分析阶段，风险预防计划制定范围内或其邻近研究区域内土地覆被认知的必要基础。
该类研究对象数据，是风险预防计划制定阶段内暴露于灾害中的资产与人员的（符合条件且非穷尽式）数据快照。该类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直接复用：研究对象会根据实际需求，依托最新数据源重新计算生成。
