Facts

Profile RED Modeling with bands 1, 2, 3, 5 and 6 Dark bottoms represent a rocky platform ~0.5 m Here they come out shallower than their brighter surrounding Brighter bottoms exhibit a distinctly green spectral signature	Profile RED Modeling with bands 1, 2, 3, and 5 Here dark bottoms are modeled at ~same depth as brighter surrounding All depths are overestimated in comparison

Sewage outfall

TCC bands 2, 3 and 5 Yellow band is spiked by the pollution	Computed depth
	There is severe depth underestimation where band 5 is polluted

System noise and pollution

Profile Black
TCC for bands Blue, Green and Yellow

System noise

System noise is apparent
- it is lowest for the 4x4 sum-aggregated Panchro channel
- it is maximum for the Purple channel
- starting at 4.5 km, it becomes extreme : what's that?
- Red band is "rotten"
Altogether, this is a noisy image, not suitable for Smart-Smoothing

Sewage

At ~3.85 km, the profile overpasses the sewage outfall
- Blue, Green, Pan, Yellow and red bands are affected
- Pollution starts at ~3.1 km in Yellow band

Raw radiances along Profile Black

Results

Profile Yellow The level of radiances is extremely low: bottoms are very dark This entails poor performances	Profile Yellow Computed depth and water column corrected reflectances for bands 1, 2 and 3
Computed depth in centimeters	Color composite of normalized water column corrected bands 1, 2 and 3 histogram equalization enhancement
image WZ Green is mapped to 3: most of this image has bottom detection in only Purple, Blue and Green bands: computed depth is less accurate Yellow is mapped to 5: areas where Purple, Blue, Green and Yellow bands have bottom detection: computed depth should be more accurate (apart from the pollution problem) One may use this image to run separate seatruth regressions	The sewage outfall causes depth under-estimation in its surrounding Threshold at 1.5 on Yellow band is quite low. And it shows in the image above. Results might be improved by raising its value.

The PAN band was not used at all
Not worth giving you any of the above :

next see when using the Panchro band
and a proper coverage
of deep water areas and of land areas
