>Lorenzo,

>As a convenience someone changed r.in.gdal to use band names derived

>changing gets the altered names.
>
>>and I must change the name of 2 files.
>>I read the QuickBird specification and the bands are blue, green, red.

>But what does it say in the TIFF file? It doesn't really matter what it
>says in the quickbird specficiation if they produce confusing TIFF files.
>What is the "tiffinfo" report for the files in question?

YOU see the bands:
1st band is BAND_B (BLUE)
2nd band is BAND_G (GREEN)
3th band is BAND_R (RED)
4th band is BAND_N (NEAR IR)
Quick Bird has this format but gdal and grass read only .TIF files
without reading .IMD file.
The BAND_B for gdal is BAND_RED and BAND_R is BAND_BLUE. This is wrong
