Simple download service (Atom) of the dataset: All of the knowledge on flooding areas in Côte-d’Or

This layer represents the strongest expansion zones in Côte d’Or (modelled Q100, historical floods, PPR reference floods, HGM).

For the same watercourse, several zonings may exist. It is then necessary to refer to the study or mapping for more information.

This layer was formed by agglomeration of these spatial data. The genealogy of objects varies as well as their accuracy, ranging from 1/5000 for modelling during PPR to 1/25000 for historical flooding.
This layer is continuously updated.

该图层表征法国科多尔省（Côte d’Or）范围内的最强洪水扩张区，涵盖经建模的Q100洪水、历史洪水、PPR参考洪水及HGM数据。针对同一河道，可能存在多套分区方案，此时需参考对应研究或地图以获取更多详细信息。该图层由上述空间数据聚合生成，数据要素的溯源信息与精度均存在差异：PPR建模所用数据比例尺为1/5000，历史洪水数据比例尺则为1/25000。该图层处于持续更新状态。
