Dataset Direct Download Service (WFS): Specific issues taken into account in the PPRN flooding of the river Charente of the commune of Romegoux 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.

概而言之，承险体指受致灾因子（hazard）威胁、且可能遭受其影响或破坏的人员、财产、活动、文化或环境遗产要素。某一研究对象对致灾因子的敏感性被称为‘易损性’（vulnerability）。
该对象类别涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中涉及的全部研究对象。研究对象为具有时间属性的实体，其是否纳入考量取决于风险预防计划的研究目标，以及其对所研究致灾因子的易损性。因此，某PPR研究对象是否纳入考量，取决于当前所应对的致灾因子类型。
在开展研究对象分析阶段，上述要素构成了在研究区域内或其邻近区域制定风险预防计划所需的土地覆被认知基础。
该类研究对象数据呈现了风险预防计划制定阶段，暴露于致灾因子中的资产与人员的（具象化且非穷尽式）快照。此类数据在风险预防计划获批后不再更新。实际应用中该类数据亦不再直接使用：研究对象需根据需求，依托最新数据源重新计算生成。
