My gdal fu is weak and I need help! ;)
I'm creating a mosaic in geotiff from hundreds of ecw. I created a list of all my rasters and used this command:
gdal_merge -o c:\temp\output_image.tif -q -v --optfile c:\temp\rasterlist.txt
It's working, but I'd like now to create one with only the red band. Is it possible to do it with gdal_merge?
