DESCRIPTION
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
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 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.
−−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.
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.
EXAMPLES
Example 1: Convert to Float32 data type
$ gdal raster set−type −−datatype Float32 byte.tif float32.tif −−overwrite
