摘要: An estimation of bathymetry in the optically complex lagoon New Caledonia was performed from multispectral satellite images. Bathymetric obtained with Medium Resolution Imaging Spectrometer (MERIS) images acquired at different dates. The method is based on rotation a pair spectral bands (red and green bands). One resulting only depth-dependent when other reflectance-dependent. A comparison made compilation bathymetric data Institut de Recherche pour le Developpement (IRD) Noumea measurements. This study shows influence variation water composition, then diffuse attenuation, results. chlorophyll concentration, correlated explains error map. results show that this remains valid under low (<;1 mg · m-3) constant concentration (<;10% variation) to limit RMSE image (<; 15.5%).
