GDAL-RASTER-SELECT(1) GDAL GDAL-RASTER-SELECT(1) NAME gdal-raster-select - Select a subset of bands from a raster dataset Added in version 3.11. SYNOPSIS Usage: gdal raster select [OPTIONS] <INPUT> <OUTPUT> <BAND> Select a subset of bands from a raster dataset. Positional arguments: -i, --input <INPUT> Input raster dataset [required] -o, --output <OUTPUT> Output raster dataset [required] -b, --band <BAND> Band(s) (1-based index, 'mask' or 'mask:<band>') [1.. values] [required] Common Options: -h, --help Display help message and exit --json-usage Display usage as JSON document and exit --config <KEY>=<VALUE> Configuration option [may be repeated] --progress Display progress bar Options: -f, --of, --format, --output-format <OUTPUT-FORMAT> Output format ("GDALG" allowed) --co, --creation-option <KEY>=<VALUE> Creation option [may be repeated] --overwrite Whether overwriting existing output is allowed --mask <MASK> Mask band (1-based index, 'mask', 'mask:<band>' or 'none') Advanced Options: --if, --input-format <INPUT-FORMAT> Input formats [may be repeated] --oo, --open-option <KEY>=<VALUE> Open options [may be repeated] DESCRIPTION gdal raster select can be used to select and re-order a subset of raster bands from a raster dataset. This subcommand is also available as a potential step of gdal raster pipeline Standard options -f, --of, --format, --output-format <OUTPUT-FORMAT> Which output raster format to use. Allowed values may be given by gdal --formats | grep raster | grep rw | sort --co <NAME>=<VALUE> Many formats have one or more optional creation options that can be used to control particulars about the file created. For in- stance, the GeoTIFF driver supports creation options to control compression, and whether the file should be tiled. May be repeated. The creation options available vary by format driver, and some simple formats have no creation options at all. A list of op- tions supported for a format can be listed with the --formats command line option but the documentation for the format is the definitive source of information on driver creation options. See Raster drivers format specific documentation for legal cre- ation options for each format. --overwrite Allow program to overwrite existing target file or dataset. Otherwise, by default, gdal errors out if the target file or dataset already exists. --band <BAND> Select one or several input bands. Bands are numbered from 1. Multiple values may be selected to select a set of input bands to write to the output file, or to reorder bands. The special value mask means the mask band of the first band of the input dataset. The mask band of any band can be specified with mask:<band>. A mask band selected with --band will become an or- dinary band in the output dataset. --mask <BAND> Select one input band to create output dataset mask band.. Bands are numbered from 1. The special value mask means the mask band of the first band of the input dataset. The mask band of any band can be specified with mask:<band>. <BAND> can be set to none to avoid copying the global mask of the input dataset if it exists. Otherwise it is copied by default, unless the mask is an alpha channel, or if it is explicitly selected to be a regular band of the output dataset (--band mask) GDALG OUTPUT (ON-THE-FLY / STREAMED DATASET) This program supports serializing the command line as a JSON file using the GDALG output format. The resulting file can then be opened as a raster dataset using the GDALG: GDAL Streamed Algorithm driver, and ap- ply the specified pipeline in a on-the-fly / streamed way. EXAMPLES Example 1: Reorder a 3-band dataset with bands ordered Blue, Green, Red to Red, Green, Blue $ gdal raster select --band 3,2,1 bgr.tif rgb.tif --overwrite Example 2: Convert a RGBA dataset to a YCbCR JPEG compressed GeoTIFF $ gdal raster select --band 1,2,3 --mask 4 --co COMPRESS=JPEG,PHOTOMETRIC=YCBCR rgba.tif rgb_mask.tif AUTHOR Even Rouault <even.rouault@spatialys.com> COPYRIGHT 1998-2025 Jul 12, 2025 GDAL-RASTER-SELECT(1)
