GDAL-RASTER-RESIZE(1) GDAL GDAL-RASTER-RESIZE(1) NAME gdal-raster-resize - Resize a raster dataset Added in version 3.11. SYNOPSIS 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] [not available in pipelines] -o, --output <OUTPUT> Output raster dataset [required] [not available in pipelines] 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 or warning message) [not available in pipelines] Options: -f, --of, --format, --output-format <OUTPUT-FORMAT> Output format ("GDALG" allowed) [not available in pipelines] --co, --creation-option <KEY>=<VALUE> Creation option [may be repeated] [not available in pipelines] --overwrite Whether overwriting existing output dataset is allowed [not available in pipelines] Mutually exclusive with --append --append Append as a subdataset to existing output [not available in pipelines] 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] [not available in pipelines] --oo, --open-option <KEY>=<VALUE> Open options [may be repeated] [not available in pipelines] DESCRIPTION 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 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. PROGRAM-SPECIFIC OPTIONS -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. --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 percent- age 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. STANDARD OPTIONS --append Append input raster as a new subdataset to an existing output file. Only works with drivers that support adding subdatasets such as GTiff -- GeoTIFF File Format and GPKG -- GeoPackage raster This also creates the output dataset if it does not exist yet. --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 sim- ple formats have no creation options at all. A list of options sup- ported 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 for- mat specific documentation for legal creation options for each for- mat. --if, --input-format <format> Format/driver name to be attempted to open the input file(s). It is generally not necessary to specify it, but it can be used to skip automatic driver detection, when it fails to select the appropriate driver. This option can be repeated several times to specify sev- eral candidate drivers. Note that it does not force those drivers to open the dataset. In particular, some drivers have requirements on file extensions. May be repeated. --oo, --open-option <NAME>=<VALUE> Dataset open option (format specific). May be repeated. -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 --overwrite Allow program to overwrite existing target file or dataset. Other- wise, by default, gdal errors out if the target file or dataset al- ready exists. RETURN STATUS CODE The program returns status code 0 in case of success, and non-zero in case of error (non-blocking errors emitted as warnings are considered as a suc- cessful execution). EXAMPLES Example 1: Resize a dataset to 1000 columns and 500 lines using cubic resam- pling $ 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 AUTHOR Even Rouault <even.rouault@spatialys.com> COPYRIGHT 1998-2026 Jun 05, 2026 GDAL-RASTER-RESIZE(1)
