OpenEV now available!
All the above was done before I could use OpenEV

Channel_6Special effects : mask mSE	Channel_7 : Green and Red solutions -Lm/0001.0/001.0/001.0/001.0/255.0
Channel_9 : Z in decimeters chequered	Channel_11 : Average bottom brightness B chequered
Until the image is licensed, 4SM writes out chequered results	Cells are 500*500 pixels. The license cost for this im ageis 758_Euros
Channel_35 : Z in centimeters
Channel_11 Average bottom brightness B	Circa Row_3300 and Line_1900, in this all-terrigeneous environment (any submerged vegetation?) , Yellow_Brown hues smack of more turbid waters (like if waters flowing Southwards), and therefore entails some depth underestimation South of Line_3100 : Reddish hues indicate areas where optical calibration applies comfortably
Channels_28_26_25 TOA TCC deglinted	Channels_28_26_25 BOA TCC WCC View as if at "low tide". Shallow substrates are much darker than soils on land. Lmred=1. Water turbidity along the water lineshows up clearly; this causes depth underestimation.
TCC raw 16U data Waters there might be less clear. Darker patches: is there any upwelling?	Water turbidity causes depth underestimation by the Red solution optically deep waters much closer to the waterline
Channels_41_39_3 : TCC raw 16U data What's this fabric in the raw data? This is a very bad noise, heavy smoothing required.	Channel_42 : NIR band Why is the NIR signal smoothed like that?
Profile Blue Raw radiances are very noisy. This noise is NOT correlated among spectral bands, therefore it is not caused by specular reflection. This is appalling	Raw DN 12-bits radiances, on a scale of 0-4095, are very noisy, noise ranges over ~15 DNs, even exhibiting "worm-like features" which remind me of fancy wavelet transforms or the like. Panchro in channel_3 is even more noisy, ranging over ~40 DNs, although it is over-sampled from 0.5 to 2 m GSD. Or did I miss something?
Atmospheric adjacency effect This is consistent with a fairly strong atmospheric adjacency effect which needs absolutely to be "de-glinted". "Deglinting" the atmospheric adjacency effect, like if it was mere specular reflection at the sea surface, actually works very well after all, it is caused by the multiple diffusion of the land-reflected photons away from the direct field of view of the sensor telescope this diffusion is caused by the abundance of aerosols	Atmospheric path radiance For a NIR band to score 150 over a range of 0-4096, it requires quite a lot of aerosols. For a NIR band to score 34 over a range of 0-255 (where "bright" Tuscany terrigeneous beaches score ~255), it requires quite a lot of aerosols in august. This reminds me of Abu Dhabi overcast skies. This is consistent with a fairly strong adjacency effect which needs absolutely to be "de-glinted".

Massimo: Heavy smoothing of costly 2 m GSD data does not make sense to me.
Why not try Landsat 8 data, pansharpened to 15 m GSD, see if it can save you money for your project of monitoring Tuscany's coastal erosion?

Note: the PLEIADES Panchromatic band should be discarded altogether
