Map Viewing Service (WMS) of the dataset: Territories of Charente-Maritime flooded during storm Xynthia

This geographic layer is the perimeter of all flooded land during storm Xynthia of February 27-28, 2010. The purpose of this layer is to serve as a memory document for people and land use decision makers. It is specified that the sources of flooding are multiple: submersion by sea and indirect submersion by obstruction of the outlets to the sea. The maps carried out in the marshes are imprecise in view of the lack of knowledge of these areas during the event. Similarly, the reference scale (1/25000) translates that the exact list of flooded areas is not mapped to the plot.本地理图层为2010年2月27日至28日辛西娅风暴（Xynthia）期间所有受淹陆地的边界范围。本图层旨在为民众及土地利用决策人员留存历史参考档案。本次洪涝的成因被明确为多种类型：海水漫溢，以及因入海排水口受阻引发的间接淹没。鉴于事件发生期间对沼泽区域的调研资料不足，该区域的测绘成果精度欠佳。同理，该图层采用1:25000的参考比例尺，这意味着无法以宗地为单位精准绘制全部受淹区域的完整清单。
