Shallow water depth and bottom type from satellite image   Further to Lyzenga's and Stumpf's methods, most existing empirical methods still need the following and only deliver shallow water depths atmospheric correction conversion into units of reflectance an existing depth sounding dataset that covers faithfully the whole ranges of bottom brightnesses and shallow depths segmentation of shallow areas into several bottom brightness classes, irrespective of depth specify a, b and c for each class: Z= aX...
