Coastal migration from field data Original (1250K-3M)

Pan-European coastline-migration map at zoomable scale. The map is collated and harmonized from field-monitoring data and aerial photography provided by partners of EMODnet Geology. Where no such coastline-migration data were available, information from the EUROSION project is provided. For remaining gaps, please consult the coastline-migration map based on satellite data. The main attributes denote degree of landward (by erosion or submergence) or seaward (by accretion or emergence) change. In the visualization provided, three classes are distinguished: landward migration, stable coastline, seaward migration. The criterion for stable coastlines is ≤0.5 meter net change per year over a 10-year period. The current version was finalized in January 2021.可缩放比例尺的泛欧洲海岸线迁移地图。该地图由欧洲海洋观测与数据网络（EMODnet）地质分部的合作伙伴提供的野外监测数据与航空摄影资料整合并标准化后编制而成。若未获取此类海岸线迁移数据，则采用欧洲侵蚀（EUROSION）项目的相关信息。对于仍存在的数据空白，可参考基于卫星数据的海岸线迁移地图。该数据集的核心属性表征海岸向陆（通过侵蚀或淹没）或向海（通过淤积或出露）的变化幅度。在所提供的可视化成果中，共划分三类海岸：向陆迁移海岸、稳定海岸与向海迁移海岸。稳定海岸的判定标准为：十年周期内年净变化量不超过0.5米。当前版本于2021年1月最终定稿。
