EMODnet Bathymetry - World Coastline version 2022

The EMODnet Bathymetry World Coastline is available as a WFS service from EMODnet Bathymetry. The service URL is: https://ows.emodnet-bathymetry.eu/wfs. The layer contains vector lines derived from land polygons available from OpenStreetMap. The original source url is https://osmdata.openstreetmap.de/. Parts of these polygons have been modified for use in EMODnet Bathymetry.
In addition to the OSM EMODnet default coastline, three sub-layers are available as part of the EMODnet world coastline service. These sub-layers contain the best-estimate coastlines for Europe determined by Dutch research institute Deltares from satellite data (typically Sentinel-2 and Landsat-8) and in combination with the Global Tide Surge Model (GTSM) processed into digital coastlines for the European seas at LAT (Lowest Astronomical Tide), MSL (Mean-Sea-Level), and MHW (Mean-High-Water). The level of detail is bound to the resolution of the satellite sensor (e.g. 10m for Sentinel-2). The latest December 2020 version now covers the entire coastline of Europe.
A detailed paper is available describing the methodology used to determine the three versions of the satellite derived coastline:

EMODnet测深世界海岸线可通过EMODnet测深提供的WFS服务获取，服务地址为：https://ows.emodnet-bathymetry.eu/wfs。该图层包含源自OpenStreetMap（OSM）公开的陆面多边形矢量线，原始数据源地址为https://osmdata.openstreetmap.de/。部分多边形已针对EMODnet测深项目的使用需求进行了适配修改。
此外，除OSM版EMODnet默认海岸线外，EMODnet世界海岸线服务还包含三个子图层。这些子图层包含由荷兰研究机构Deltares基于卫星数据（通常为Sentinel-2与Landsat-8）结合全球潮汐风暴潮模型（Global Tide Surge Model, GTSM）生成的欧洲最优估算海岸线，已处理为欧洲海域在最低天文潮（Lowest Astronomical Tide, LAT）、平均海平面（Mean-Sea-Level, MSL）及平均高潮位（Mean-High-Water, MHW）下的数字化海岸线。其细节分辨率匹配卫星传感器的分辨率（如Sentinel-2的10米）。2020年12月发布的最新版本已覆盖欧洲全部海岸线。
另有一篇详细论文阐述了上述三种卫星衍生海岸线的生成方法，论文链接为：https://emodnet.ec.europa.eu/sites/emodnet.ec.europa.eu/files/public/20201219_emodnet_bathymetry_satellite_derived_coastline_report.pdf
