comment How to add color interpretation for raster bands using GDAL?
I've asked my boss, and I can't publish data :-(. I actually could mix the files with a standalone code, that copies band by band the input files in the output. I'd like to do it with gdal_merge. My poblem is I can't set RGB color interpretation for the output file with gdal_merge.

Thanks for your tip! I want to merge 3 single band geotiffs in one 3-band geotiff. My problem is the output of gdal_merge is actually empty (pixels = 0). I can't use that output for anything.

Mmm... thanks for the response. I'm trying those options. Seems than I can't use PHOTOMETRIC=rgb because my datatype is not int. But I'm on it...

Mmmm, ok. If I warp them to create north up rasters, I can build the VRT, and add ColorInterp where needed, buy I still get gray, undefined, undefined. I need to create a color table for first band, but I don't know how. I'll update the question.

I actually did that, but I get "ERROR 6: SetColorTable() not supported for multi-sample TIFF files.". And I get 0 for all pixels. I'm not sure about the meaning of this error.

No,they all have the same geotransforms,but they're no north-up rasters (rotation parameters are not 0). And gdalbuildvrt does not support rotated geo transforms. I don't want to warp them.

I tried, but my raster files are rotated...
