Negative Bottom Contrast and Water Volume Reflectance Syntax Z See above that some local areas under mask_4 are assigned to deep water This is wrong of course Rather, low light areas deserve special attention Negative bottom contrast is when Ls-Lsw becomes ~null or even negative This happens frequently with the Blue bands in "blue" waters as Lwblue cannot be disregarded, Water volume reflectance can reach in excess of 10% in a blue band -Lw/0010.6/001.5/000.0/000.0 -Z/MSL0.00/N_1/RLBgb1.090/Mask_4 | ||||||
We want more bottom reflected photons to reach the sensor! | ||||||
