Modeling
All modeling was performed using the "PAN solution".
This means: Purple, Blue and Green bands against PANchro band.
This means: Yellow, Red, RedEdge, NIR1 and NIR2 play no role in modeling.

Results by Mobley et al, 2005 using Ocean PHILLS image The profile shows that the oolithic ridge is ~6 m high, from 3 m at the top to 9 m at the base

Profiles

Profile Orange

Profile Red

The oolithic ridge is located between waypoints 1 and 2 in all four sections.
- its spectral water column corrected signature is high in the Purple channel
The profile shows that the oolithic ridge is ~6 m high, from 5 m at the top to 11 m at the base
Please note the 15-20 m deep through in Profile_Red between waypoints A2 and A3, with an extremely green bottom signature.

Profile Black

Please note that the water column corrected reflectances have been divided by 2 in order to accomodate the very bright reflectances at the end of Profile_black (section A2)

System noise

these profiles are very noisy, in spite of strong smart-smoothing.
- this noise is seen to increase steadily from shallow to deeper (much more than with a "Green" solution).
- this comes with the "PAN solution", and reduces the "precision" on retrieved depths.

The advantage of the "PAN" solution

In 4SM, and in the absence of a PAN channel,
- first the "RED solution" is operated for pixels that carry a Red signal that is stronger than the Red threshold value.
- then the "YELLOW solution" is operated for pixels that carry a Yellow signal that is stronger than the Yellow threshold value.
- then the "GREEN solution" is operated for pixels that carry a Green signal that is stronger than the Green threshold value.
This means that gaps show off atboth transitons
- Red_to_Yellow
- Yellow_to_Green
Using the "PAN solution" for all pixels yields a depth raster without any gap, much to the relief of the end-user!

Georeferencing: this image in a geographic projection (Lat/Long):
- see details in 09DEC07154605-M2AS-052963315020_01_P001.IMD in zipfile
- UL origin is -76.232682 and 23.871708, as reported by OpenEV for tile R1C1
- pixel size are 1.7999999948e-05 and 1.80000000012e-05, as reported by OpenEV for tile R1C1

This zipfile contains the following:

lsiwvmp_20091209_Zcm.tif one S16 channel, retrieved depth in centimeters, as is: uncorrected for tide
lsiwvmp_20091209_WCC.tif seven U8 channels, TOA water column corrected reflectances, scaled 0-250
- channels 1 to 6 are water column corrected Purple, Blue, Green, PAN, Yellow and Red
- channel 7 maps the "solution":
  - 4 for the "PAN solution",
  - a very few 3 for the "Green solution" where the PAN signal is less than the threshold.
