The data

TCC deglinted BOA

Glint regressions, based on SWIR band 7,

Green band, BOA deglinted

Blue band, BOA deglinted
Optical calibration

Optical calibration confirms LUT mapping results 
Map of the ratio Kblue/Kgreen   see legend

Map of K2/K3 on reef flat:
how surprising

Map of K2/K3 on mangrove/river discharge:
coastal waters as expected


How weird
OIII water type on the reef flat
  • 1-5 m: Kblue~=Kgreen: K2/K3=0.9
  • reef crest covered by 1 m of water
This is demonstrated
and confirms the above LUT mapping result

Quite interesting
Coastal waters along the coast
  • 0-4 m: Kblue>>Kgreen: K2/K3~1.3
    • that is Coastal C5 water type
  • >4 m:  Kblue~=Kgreen: K2/K3~0.9
    • that is Coastal C1 water type

Continue to Optical calibration

work in progress
