Dataset Direct Download Service (WFS): Specific issues of the PPRN flooding by overflow of the Charente River in the commune of Fontcouverte 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.

简言之，风险承灾体指受灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化遗产或环境遗产要素。某一对象对灾害的敏感程度被称为‘脆弱性（vulnerability）’。

本对象类别涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中涉及的全部对象。此处的‘对象’为具有时间属性的实体，其是否纳入考量取决于RPP的目标，以及其针对所研究灾害的脆弱性。因此，某一PPR对象是否可被纳入，需结合当前处理的灾害类型而定。

在开展对象分析时，上述要素构成了在研究区域及其周边区域制定RPP所需的土地覆被（land cover）认知基础。

风险预防计划制定阶段，相关对象数据呈现的是（具有示意性但非穷尽式的）受灾害影响的资产与人员快照。该类数据在RPP获批后不再更新，实际应用中亦不再直接复用：需依托最新数据源，按需重新计算相关对象信息。
