gdal-raster-select - Select a subset of bands from a raster
dataset
Added in version 3.11.
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]
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
- --co
<NAME>=<VALUE>
- Many formats have one or more optional creation options that can be used
to control particulars about the file created. For instance, 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 options
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 creation 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 ordinary 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)
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 apply the specified pipeline in a on-the-fly / streamed way.
$ gdal raster select --band 3,2,1 bgr.tif rgb.tif --overwrite
$ gdal raster select --band 1,2,3 --mask 4 --co COMPRESS=JPEG,PHOTOMETRIC=YCBCR rgba.tif rgb_mask.tif
