  abstract = {{A}ccurate and reliable bathymetric data are needed for a wide diversity of marine research and management applications. {S}atellite-derived bathymetry represents a time saving method to map large shallow waters of remote regions compared to the current costly in situ measurement techniques. {T}his study aims to create very high-resolution ({VHR}) bathymetry and habitat mapping in {M}ayotte island waters ({I}ndian {O}cean) by fusing 0.5 m {P}leiades-1 passive multispectral imagery and active {ICES}at-2 {L}i{DAR} bathymetry. {ICES}at-2 georeferenced photons were filtered to remove noise and corrected for water column refraction. {T}he bathymetric point clouds were validated using the {F}rench naval hydrographic and oceanographic service {L}itto3{D}({R}) dataset and then used to calibrate the multispectral image to produce a digital depth model ({DDM}). {T}he latter enabled the creation of a digital albedo model used to classify benthic habitats. {ICES}at-2 provided bathymetry down to 15 m depth with a vertical accuracy of bathymetry estimates reaching 0.89 m. {T}he benthic habitats map produced using the maximum likelihood supervised classification provided an overall accuracy of 96.62%. {T}his study successfully produced a {VHR} {DDM} solely from satellite data. {D}igital models of higher accuracy were further discussed in the light of the recent and near-future launch of higher spectral and spatial resolution satellites.},
