How can we assign the band B1, B2 and B3 of XS to the Red Green Blue colour so that the natural green colour can be reproduced?
The transformation formulas used for natural green colours are much more complex. The process is not automatic. First of all, one does a special radiometric enhancement. Then, the process is a polynomial transformation from bands B1, B2, B3 to new R, G, B bands. The coefficients of this transformation depend on the original radiometry fand landscape. The final step is manual adaptation.
