Hi!
I need merge two images - the first image is mutiband and second image
is singleband.
Can I do this operation with gdal_merge or gdal_merge works only with
images with same number of bands?
What utility from gdal library I can use for separate multiband image
into some singleband images?
Denis,
You can use gdal_translate to extract a subset of bands from an image.
The following would copy just band 2 from in.tif into a new file, out.tif.
gdal_translate -b 2 in.tif out.tif
The following would take the first three bands from a 4 band input file.
gdal_translate -b 1 -b 2 -b 3 rgba.tif rgb.tif
Best regards,
