gdal-raster-resize - Resize a raster dataset
Added in version 3.11.
Usage: gdal raster resize [OPTIONS] <INPUT> <OUTPUT>
Resize a raster dataset without changing the georeferenced extents.
Positional arguments:
-i, --input <INPUT> Input raster datasets [required]
-o, --output <OUTPUT> Output raster dataset [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]
-q, --quiet Quiet mode (no 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
Mutually exclusive with --append
--append Append as a subdataset to existing output
Mutually exclusive with --overwrite
--resolution <xres>,<yres> Target resolution (in destination CRS units)
Mutually exclusive with --size
--size <width[%]>,<height[%]> Target size in pixels (or percentage if using '%' suffix) [required]
Mutually exclusive with --resolution
-r, --resampling <RESAMPLING> Resampling method. RESAMPLING=nearest|bilinear|cubic|cubicspline|lanczos|average|mode (default: nearest)
Advanced Options:
--if, --input-format <INPUT-FORMAT> Input formats [may be repeated]
--oo, --open-option <KEY>=<VALUE> Open options [may be repeated]
gdal raster resize can be used to resize a raster dataset without
changing the georeferenced extents.
This subcommand is also available as a potential step of gdal raster
pipeline
-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, --creation-option <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.
--resolution <xres>,<yres>
Added in version 3.12.
Set output file resolution (in target georeferenced units).
Mutually exclusive with --size.
--size <width[%]>,<height[%]>
Set output raster width and height, expressed in pixels, or
percentage if using the % suffix. If the width or the height
is set to 0, the other dimension will be guessed from the
computed resolution.
Mutually exclusive with --resolution.
-r, --resampling <RESAMPLING>
Resampling method to use. Available methods are:
nearest: nearest neighbour resampling (default, fastest
algorithm, worst interpolation quality).
bilinear: bilinear resampling.
cubic: cubic resampling.
cubicspline: cubic spline resampling.
lanczos: Lanczos windowed sinc resampling.
average: average resampling, computes the weighted average of
all non-NODATA contributing pixels.
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 apply the specified pipeline in a on-the-fly / streamed way.
Example 1: Resize a dataset to 1000 columns and 500 lines using cubic
resampling
$ gdal raster resize --size=1000,500 -r cubic in.tif out.tif --overwrite
Example 2: Resize a dataset to half size using cubic resampling
$ gdal raster resize --size=50%,50% -r cubic in.tif out.tif --overwrite

DESCRIPTION
gdal raster resize can be used to resize a raster dataset without

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, --creation-option <NAME>=<VALUE>
