gdal_merge.py want input bands of a multiband tiff pathed via the --optfile option?
I am merging a large list of .tifs via a subprocess.call in python:
gdal_merge.py -o "target" --optfile "fileIn"
where "fileIn" is a list of input files. But playing around I can't seem to find how to reference example.tif Band_1, for example. So even more simply, how do you call a specific band of a multiband geotiff in gdal?
