Dataset Direct Download Service (WFS): Surface issues taken into account in the PPRN flooding by overflow of the Charente River in the commune of Montils 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，承灾体指的是受灾害威胁、并可能因灾害遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一研究对象对灾害的敏感性被称为“脆弱性（vulnerability）”。

本对象类别涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部研究对象。所谓研究对象，是一类具有明确时间属性的实体，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，是否将某一风险预防计划研究对象纳入分析，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，上述要素构成了研究区域及其周边区域内，风险预防计划编制所需的土地覆被认知基础。

研究对象相关数据，是风险预防计划编制阶段内，暴露于灾害威胁下的资产与人员的（符合条件但非穷尽式）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使用：研究对象需结合最新数据源，根据实际需求重新计算生成。
