Very High-Resolution Satellite-Derived Bathymetry and Habitat Mapping Using Pleiades-1 and ICESat-2

Accurate and reliable bathymetric data are needed for a wide diversity of marine research management applications. Satellite-derived bathymetry represents time saving method to map large shallow waters remote regions compared the current costly in situ measurement techniques. This study aims create very high-resolution (VHR) habitat mapping Mayotte island (Indian Ocean) by fusing 0.5 m Pleiades-1 passive multispectral imagery active ICESat-2 LiDAR bathymetry. georeferenced photons were filtered remove noise corrected water column refraction. The point clouds validated using French naval hydrographic oceanographic service Litto3D® dataset then used calibrate image produce digital depth model (DDM). latter enabled creation albedo classify benthic habitats. provided down 15 with vertical accuracy estimates reaching 0.89 m. habitats produced maximum likelihood supervised classification an overall 96.62%. successfully VHR DDM solely from satellite data. Digital models higher further discussed light recent near-future launch spectral spatial resolution satellites.
