Dataset Direct Download Service (WFS): Issue Linear of the Plan for the Prevention of Predictable Natural Flood Risks of the Indre Valley in the Indre-et-Loire

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.

总体而言，受险目标指的是受危险威胁、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。某一对象针对某一危险的敏感程度被称为‘脆弱性（vulnerability）’。

该对象类别涵盖了风险预防计划（Risk Prevention Plan，以下简称RPP）研究中涉及的全部对象。此处的‘对象’指具备时间属性的实体，其是否纳入考量取决于RPP的编制目标，以及其针对所研究危险的脆弱性。因此，是否将某一RPP相关对象纳入分析，需结合当前所针对的危险类型而定。

上述要素构成了在对象分析阶段，针对研究区域及其周边开展RPP编制所需的土地覆被认知基础。

该对象相关数据呈现了风险预防计划编制阶段，受危险威胁的各类资产与人员的（可呈现且非穷尽）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被直接使用：相关对象会根据需要，结合最新数据源重新计算生成。
