OK Excuse me for method but I want to understand.
In old gdal 1.1.8 I had the tiff files with number suffix
filetiff.1
filetiff.2
filetiff.3
filetiff.4
and after I choose the order for my BGR (blue-red-green for
quickbird). I choose 321 for my output.
From gdal 1.1.9 the tiff file have a color suffix.
filetiff.red
filetiff.green
filetiff.blue
filetiff.alpha
and I must change the name of 2 files.
I read the QuickBird specification and the bands are blue, green, red.
With the number suffix I worked with GDAL and GRASS like ENVI for
RGB images...
Thanx
