I'm looking to extract shorelines from satellite images. To find a suitable method I need to compare various methods of automatic shoreline extraction methodologies. If you have any suggestions please leave in reply...
I don't know about this tool bit you could use Raster calculator to compute the indices.
A faster way would be to use R and the function tasseledCap from the RSToolbox library. Here is the link to the function: https://rdrr.io/cran/RStoolbox/man/tasseledCap.html
