![]() ![]() ![]() ![]() | As of 2021, I am investigating a 4SM-LUT approach Passive optical calibration, satellite derived bathymetry, water column correction and bottom typing of shallow water areas using remote sensing imageries. Use passive hyperspectral or multispectral satellite images to retrieve both SDB depth and spectral reflectance of shallow bottom, ready for bottom typing, ahead of any field work: no need for field data. ![]() ![]() Panchromatic ![]() And the winner is Uncertainty on depth Empirical vs Analytical 2K_Jerlov 4SM_LUT ![]() ![]() home page continued | ![]() ![]() ![]() ![]() |
