Map Viewing Service (WMS) of the dataset: Ad hoc issues of the PPRN of the municipality of Criel-sur-Mer — Seine-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，风险承险体是指受到危险威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象针对特定危险的敏感度被称为“脆弱性（vulnerability）”。 该对象类别涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中涉及的全部研究对象。此处的“研究对象”为带有时间属性的实体，其是否被纳入考量取决于RPP的编制目标，以及其针对所研究危险的脆弱性。因此，是否纳入某一RPP研究对象，需根据所针对的危险类型而定。 在开展研究对象分析的阶段，上述要素构成了在研究区域内或其周边编制RPP所需的土地覆盖认知基础。 此类研究对象数据，是风险预防计划编制阶段内暴露于危险中的资产与个体的（有限但非穷尽的）快照式记录。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沿用，而是会根据需要采用最新数据源重新计算得到相关研究对象信息。
