Dataset Direct Download Service (WFS): Linear issue of the natural flood risk prevention plan of the Val de Léré-Bannay, La Celle-sur-Loire — Nièvre (58)

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，风险承灾体指受灾害威胁、并可能因此遭受影响或破坏的人员、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"脆弱性（vulnerability）"。本对象类别涵盖了RPP研究中涉及的全部风险评估对象。所谓风险评估对象，是一类具备时间属性的实体，其是否纳入分析，取决于RPP的研究目标以及其针对所考察灾害的脆弱性。因此，PPR风险评估对象是否被纳入考量，需根据所针对的灾害类型而定。在开展风险评估对象分析的阶段，上述要素构成了研究区域及其周边区域编制RPP所需的土地覆被认知基础。风险评估对象相关数据，是RPP编制阶段内暴露于灾害中的资产与人群的（figible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：风险评估对象需根据实际需求，依托最新数据源重新计算生成。
