Resumen

Global bathymetry data is essential for coastal mapping, modeling, and management, especially in insufficiently mapped regions. Ocean surface Wave Kinematics Bathymetry from satellite data provides a solution independent of water clarity, seabed habitats, and seafloor brightness. This study presents a fully automatic, scalable, and globally applicable Wave Kinematics Bathymetry processing workflow at 100 m resolution. Validated across eleven sites, it introduces automatic post-processing that eliminates false positives by up to 80 %, reduces depth errors by an average of 4.6 m and enhances data reliability. Deployed on the AWS cloud platform, this scalable method advances efficient global coastal bathymetry mapping.
