Data and Deglinting

TOA TCC: raw image logarithmic enhancement	BOA TCC deglinted image logarithmic enhancement
Glint regressions using SWIR1 R2 values are fairly high 15 m resampling does not increase noise	Special effect mask mSE
Location of Profile_RED backdrop is a TCC of deglinted data dLsw.shp shapefile is shown	Radiances along Profile_Red

Optical calibration for the whole image

Calibration for the whole image except Bay of La Paz for bands Blue, Green, Red and NIR	Calibration for the whole image except Bay of La Paz for bands Blue, Green, PAN, NIR
K_BLUE/K_GREEN~=0.8 Jerlov water type OII+0.6	This calibration suits the whole image except Bay of La Paz

True Color Composite of BOAWCC radiances scaled 0-250 this is early March B=Coastal band in channel 34 G=Green band in channel 35 R=Blue band in channel 36	Retrieved depth backdrop of TOA TCC see legend
Maximum BOAWCC reflectance (0-1) for this scene -RM0.137/0.172/0.234/0.233/0.314/0.433/0.456 To convert BOAWCC radiances into calibrated reflectances CoastalRefectance=CoastalBOAWCC0.137/250 BlueRefectance = BlueBOAWCC0.172/250 GreenRefectance = GreenBOAWCC*0.234/250	Maximum shallow bottom reflectance (0-1) for coral sands -RM/0.310/0.380/0.440/0.550/0.560/0.670/0.700 Coral sand is approx twice brighter than brightest sands in this scene.
Average bottom brightness see legend for image B	15 m GSD, smart-smoothed not_PANsharpened: sharpening becomes redundant/pointless, thanks to: improved co-registration of the PANchromatic band with the MULTI bands (might still be improved further) combined with 15 m resampling of MULTI bands to match the PANchro GSD smart-smoothing then becomes desirable/necessary
