Simple download service (Atom) of the dataset: Specific issues of the PPRN flooding by direct flooding of the river Charente of the commune of Bussac-sur-Charente 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，风险承险体指受致灾因子威胁、并可能遭受其影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象对致灾因子的敏感程度被定义为脆弱性。
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。此处的“研究对象”指带有时间属性的实体，其是否被纳入考量取决于RPP的研究目标，以及其针对所研究致灾因子的脆弱性。因此，某一RPP研究对象是否被纳入考量，需根据所应对的致灾因子类型而定。
在开展研究对象分析的阶段，上述要素构成了风险预防计划编制所需的研究区域及其周边区域土地覆被认知的核心基础。
此类研究对象数据反映了风险预防计划编制阶段，受致灾因子威胁的资产与个体的（具象且非详尽的）现状快照。该数据在风险预防计划获批后不再更新。实际应用中该数据已不再被使用，相关研究对象可根据需要结合最新数据源重新计算生成。
