Simple download service (Atom) of the dataset: Surface issues taken into account in the PPRN flooding by overflow of the Charente River in the commune of Saintes 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，受险标的包括受灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象对灾害的敏感程度被称为“易损性（vulnerability）”。

本对象类别涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中涉及的全部研究对象。所谓“研究对象”，是指带有时间属性的实体，其是否被纳入考量取决于RPP的目标以及其针对所研究灾害的易损性。因此，某一PPR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。

在开展研究对象分析时，上述要素构成了在研究区域及其周边制定RPP所需的土地覆被认知基础。

本研究对象相关数据，是风险预防计划制定时受灾害威胁的资产与人员的（灵活且非穷尽的）快照。该数据在RPP获批后不再更新。实际应用中此类数据已不再直接使用：研究人员可根据需要，使用最新数据源重新计算相关研究对象。
