.SH DESCRIPTION
.sp
The \fBgdal_create\fP utility can be used to initialize a new raster file,
from its dimensions, band count and set various parameters, such as CRS,
geotransform, nodata value, metadata. It can be used also in special cases,
like creating a PDF file from a XML composition file.

.TP
.B \-ot <type>
Force the output image bands to have a specific data type supported by the
driver, which may be one of the following: \fBByte\fP, \fBInt8\fP, \fBUInt16\fP,
\fBInt16\fP, \fBUInt32\fP, \fBInt32\fP, \fBUInt64\fP, \fBInt64\fP, \fBFloat32\fP, \fBFloat64\fP, \fBCInt16\fP,
\fBCInt32\fP, \fBCFloat32\fP or \fBCFloat64\fP\&.
.UNINDENT

.TP
.B \-of <format>
Select the output format. Starting with GDAL 2.3, if not specified, the
format is guessed from the extension (previously was GTiff). Use the short
format name.
.UNINDENT
.INDENT 0.0
.TP
.B \-outsize <xsize> <ysize>
Set the size of the output file in pixels. First figure is width. Second one
is height.
.UNINDENT
.INDENT 0.0
.TP
.B \-bands <count>
Number of bands. Defaults to 1 if \-outsize is specified, or 0 otherwise.
.UNINDENT
.INDENT 0.0
.TP
.B \-burn <value>
A fixed value to burn into a band for all objects.  A list of \fI\%\-burn\fP options
can be supplied, one per band being written to.
.UNINDENT
.INDENT 0.0
.TP
.B \-a_srs <srs_def>
Override the projection for the output file.  The<srs_def> may be any of
the usual GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file containing
the WKT. No reprojection is done.
.UNINDENT
.INDENT 0.0
.TP
.B \-a_ullr <ulx> <uly> <lrx> <lry>
Assign the georeferenced bounds of the output file.
.UNINDENT
.INDENT 0.0
.TP
.B \-a_nodata <value>
Assign a specified nodata value to output bands.
.UNINDENT
.INDENT 0.0
.TP
.B \-mo <META\-TAG>=<VALUE>
Passes a metadata key and value to set on the output dataset if possible.
.UNINDENT
.INDENT 0.0
.TP
.B \-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.
.sp
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
\fI\%\-\-formats\fP
command line option but the documentation for the format is the
definitive source of information on driver creation options.
See \fI\%Raster drivers\fP format
specific documentation for legal creation options for each format.

.B \-if <input_dataset>
New in version 3.3.

.sp
Name of GDAL input dataset that serves as a template for default values of
options \-outsize, \-bands, \-ot, \-a_srs, \-a_ullr and \-a_nodata.
Note that the pixel values will \fInot\fP be copied.
