A time series of Landsat 8 OLIP images
at Nosy Be, Madagascar

work done in january 2021 at 15 m GSD
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=1Blue=2Green=3PAN=4Red=5NIR=6 and SWIR1=7

   peer-reviewed and published in 2017    

Ready for modeling

Map of the ratio Kblue/Kgreen see legend

TCC water column corrected V3

Ublue, Green, Blue (RGB)

pixel size is 15 m

MULTI bands are duplicated/resampled
from 30 to 15 m pixel size

No need for PANsharpening, actually.

The PAN solution achieves 
quite a nice "pansharpening"
