Hi,
I have some 4 bands tiff rasters, and like to show some layer as
combination of this 4 bands.
To have this I use the PROCESSING Layers element
like this
PROCESSING "BANDS=4,1,2"
It work greatly and show an image with false colors.
where the 4th band is returned as Red, the 1th as Green and the 2th as Blue.
But I have also some more complex formulas like this:
(4-1)/(4+1)R 2G 3B (NDVI Normalized Difference Vegetation Index)
Where the
R is obtained as the apply of this formula:
( (level of 4th band) - (level of 1th band) ) / ( (level of 4th band) +
(level of 1th band) )
and G and B channel are unchanged.
Is possible , using the processing and LUT options satisfy a so complex
formula ?
Thx,
--
