GSD 15 m Rsudio_sharpened
data are scaled into a weird range
No sweat though: 4SM is a "ratio" method
Ground truth
How sad!
 Regression October 11th 2016 vs Sonar Depths RMSE=1.64 m |  Sonar Two Days seatruth depths raster not corrected for tide 15 m GSD see depth legend |
 Regression October 11th 20146 vs DTM |  DTM resampled to 15 m GSD |
 |  ZDTM - Z4SM DTM - October 11th 20146 see legend |
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 pansharpening does not increase noise R_sharpened data include a very large offset |  can cause artifacts |
Optical calibration
for the whole image
16U data are scaled to allow for comfortable screen display
 Calibration diagram for the whole image for bands Blue, Green, Red and NIR |  Calibration diagram for the whole image for bands Blue, PAN, Red, NIR CoefKPan=1.05 |
 | Calibration diagrams are just as good for a 15m GSD pansharpened image as it is for original 30 m GSD data |
Ready for modeling
 BOA CC WCC normalized CoefNorm=7.5 (usually 2.5): shows much more BGR color composite:

Bottom typing
 SAM classified image see legend for image SAM |  Average bottom brightness see legend for image B |
| How weird that the scaling of the data by the R pan-sharpening routine does not preclude SAM mapping! | Well: that's what they mean by a "ratio" method! |
