gdal-raster-set-type1
Modify the data type of bands of a raster dataset added in version 3.11.
Overview
gdal raster set-type can be used to force the output image bands to have a specific data type. Values may be truncated or rounded if the output data type is "smaller" than the input one.
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.
Options
-
--ot, --datatype, --output-data-type <OUTPUT-DATA-TYPE> -
Output data type among
Byte,Int8,UInt16,Int16,UInt32,Int32,UInt64,Int64,CInt16,CInt32,Float32,Float64,CFloat32,CFloat64.
Options
-
--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.
-
-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. Otherwise, by default,
gdalerrors out if the target file or dataset already 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 successful execution).
Examples
Example 1: Convert to Float32 data type
$ gdal raster set-type --datatype Float32 byte.tif float32.tif --overwrite
