Dear Simen, You can refer to each band explicitly using the --A_band option. Try something like this
gdal_calc.py -A infile --A_band 1 -B infile --B_band 2 -C infile --C_band 3 --outfile outfile --calc median(A,B,C) - Chris *Dr Chris Yesson* *Institute of Zoology, Zoological Society of London* *Tel: 020 7449 6267* *email: chris.yes...@ioz.ac.uk <chris.yes...@ioz.ac.uk>**web: http://www.zsl.org/chrisyesson/ <http://www.zsl.org/chrisyesson/>* *Note: I work Mon-Thurs and do not check email on Fri* On 25 November 2014 at 07:44, Simen Langseth <simlan...@gmail.com> wrote: > Dear Respected Authors: > > I would be grateful if you could share any hints on it. > > > On Tue, Nov 25, 2014 at 4:33 PM, Simen Langseth <simlan...@gmail.com> > wrote: > >> Dear Marius Jigmond: >> >> Thanks for your attempt. >> >> Unfortunately, it is producing 3 band outfile, rather than 1 band median >> image. >> >> I could not figure out what this code computed, all the resulted 3 bands >> images are also different. >> >> I hope someone can help me. >> >> On Tue, Nov 25, 2014 at 12:09 PM, Marius Jigmond < >> mariusjigm...@hotmail.com> wrote: >> >>> Does the following work: >>> >>> gdal_calc.py -A infile --allBands=A --outfile=outfile --calc="median(A)" >>> >>> >>> ------------------------------ >>> Date: Mon, 24 Nov 2014 19:14:06 +0900 >>> From: simlan...@gmail.com >>> To: gdal-dev@lists.osgeo.org >>> Subject: [gdal-dev] gdal_calc.py: produce median raster >>> >>> >>> I have one GeoTiff file with 3 bands.
