Shallow-water Seafloor Topography Refinement Using Sentinel-2 and Multi-Source Gravity Data via a Depth-Stratified XGBoost Approach
Shallow-water depth data serve as the essential foundation for marine spatial planning and coastal engineering projects. However, due to the attenuation of spectral signals, traditional retrieval of shallow-water seafloor topography struggles to maintain high accuracy in highly turbid waters and deeper areas. Further...
