|Using the Panchromatic band for water column correction |
to derive water depth and spectral bottom signature:
Landsat 8 OLIP bandset used for this work
Purple=1, Blue=2, Green=3, PAN=4, Red=5, NIR=6 and SWIR1=7
Landsat OLI exhibits excellent radiometric quality
But: see how system noise
is transferred from the NIR band
into other bands
How sad! ====>>>>
Glint regression based on SWIR1 band
SWIR1 is quite convenient for deglinting
Glint regression based on NIR band
This is typically an image that is unsuitable for 4SM shallow water work.
Although limited (and possibly usefull) results
shall be obtained by raising the operational thresholds at very high values.
