DTM SeaTruth RMSE=0.59 m
 Z4SM vs ZDTM tide correction applied: 1.7m RMSE=0.59 m |  ZDTM-Z4SM tide correction applied: 1.7m see legend |
Data and Deglinting
 TOA TCC: raw image logaritmic enhancement |  TOA TCC deglinted image same logaritmic enhancement |

 Calibration diagram under mask_3 for bands Blue, Green, Red and NIR KBLUE/KGREEN=0.55 => Jerlov water type OIB+0.54 This calibration is fairly secure, but results shall show that bottoms are green and dark everywhere. |  Calibration diagram under mask_3 for bands Coastal, Blue, Green, and PAN [X1 & 2] vs [X3] This plot justifies that KCOASTAL must be significantly reduced from K1=0.115 m-1 to K1=0.096 m-1 This is done through the -CP... argument |
