Map Viewing Service (WMS) of the dataset: Linear issues taken into account in the PPRN field movement 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，风险承险体（stakes）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“易损性（vulnerability）”。
本对象类涵盖了风险预防规划（Risk Prevention Plan，以下简称RPP）研究中涉及的全部研究对象。此处的“研究对象（issue）”为带时间戳的实体，其是否被纳入考量取决于RPP的研究目标，以及其针对所研究灾害的易损性。因此，是否对某一RPP研究对象进行评估，需依据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，于研究区域内或其周边开展RPP编制所需的土地覆被认知基础。
本研究对象相关数据，是风险预防规划编制阶段内，暴露于灾害风险的资产与个体的（可图示且非穷尽）数据快照。该数据在RPP获批后不再进行更新。实际应用中此类数据已不再直接使用：研究对象需依据最新数据源，按需重新计算生成。
