Coastal migration from field data Original (150K-250K)

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.本数据集为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地质分部（EMODnet Geology）合作伙伴提供的野外监测数据与航空摄影资料整合协调而成。若缺乏此类海岸线迁移数据，则采用EUROSION项目的相关数据进行补充。对于仍存在数据空白的区域，可参考基于卫星数据制作的海岸线迁移地图。地图的核心属性表征了海岸向陆（由侵蚀或淹没引发）或向海（由淤积或出露引发）的变化幅度。在本次提供的可视化成果中，共划分三类海岸类别：向陆迁移型海岸、稳定型海岸与向海迁移型海岸。稳定型海岸的判定标准为：在10年观测周期内，年净变化量不超过0.5米。当前版本已于2021年1月最终定稿。
