Dataset Direct Download Service (WFS): Surface issues of PPRN flooding by overflow of the Charente river of the commune of Crazannes 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.

一般而言，受险对象是指受某一灾害威胁，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。某一对象针对灾害的敏感性被称为易损性(vulnerability)。
该对象类涵盖了RPP研究中已涉及的全部评估对象。评估对象为带有时间戳的对象，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，PPR评估对象是否被纳入考量，取决于当前所针对的一种或多种灾害类型。
在开展评估对象分析时，上述要素构成了在研究区域及其周边制定RPP所需的土地覆盖相关知识基础。
本数据集收录的评估对象数据，是风险预防计划制定阶段，暴露于灾害中的资产与人员的（符合遴选条件但非穷尽）快照。该数据在RPP获批后不再更新。实际应用中该数据已不再使用：评估对象会根据需要采用最新数据源重新计算生成。
