--help-general

Gives a brief usage message for the generic GDAL commandline options and exit.

-ro

Open the dataset in read-only. Might be useful for drivers refusing to use the dataset in update-mode. In which case, updated information will go into PAM .aux.xml files.

-a_srs <srs_def>

Defines the target coordinate system. This coordinate system will be written to the dataset. If the empty string or None is specified, then the existing coordinate system will be removed (for TIFF/GeoTIFF, might not be well supported besides that).

-a_coord_epoch <epoch>

Assign/override the coordinate epoch of the dataset, as a decimal year (e.g., 2021.3).

Added in version 3.9.

-unsetepoch

Remove the coordinate epoch of the dataset.

Added in version 3.9.

-a_ullr <ulx> <uly> <lrx> <lry>

Assign/override the georeferenced bounds of the dataset.

-a_ulurll <ulx> <uly> <urx> <ury> <llx> <lly>

Assign/override the georeferenced bounds of the dataset from three points: upper-left, upper-right and lower-left. Unlike -a_ullr, this also supports rotated datasets (edges not parallel to coordinate system axes).

Added in version 3.1.

-tr <xres> <yres>

Set target resolution. The values must be expressed in georeferenced units. Both must be positive values.

-unsetgt

Remove the georeference information.

-unsetrpc

Remove RPC information.

Added in version 2.4.

-unsetstats

Remove band statistics information.

Added in version 2.0.

-stats

Calculate and store band statistics.

Added in version 2.0.

-setstats <min> <max> <mean> <stddev>

Store user-defined values for band statistics (minimum, maximum, mean and standard deviation). If any of the values is set to None, the real statistics are calculated from the file and the ones set to None are used from the real statistics.

Added in version 2.4.

-approx_stats

Calculate and store approximate band statistics.

Added in version 2.0.

-a_nodata <value>

Assign a specified nodata value to output bands.

-unsetnodata

Remove existing nodata values.

Added in version 2.1.

-scale <value>

Assign a specified scale value to output bands. If a single scale value is provided it will be set for all bands. Alternatively one scale value per band can be provided, in which case the number of scale values must match the number of bands. If no scale is needed, it it recommended to set the value to 1. Scale and Offset are generally used together. For example, scale and offset might be used to store elevations in a unsigned 16bit integer file with a precision of 0.1, and starting from -100. True values would be calculated as: true_value = (pixel_value * scale) + offset

NOTE:

Added in version 2.2.

-offset <value>

Assign a specified offset value to output bands. If a single offset value is provided it will be set for all bands. Alternatively one offset value per band can be provided, in which case the number of offset values must match the number of bands. If no offset is needed, it recommended to set the value to 0. For more see scale.

Added in version 2.2.

-units <value>

Assign a unit to output band(s).

Added in version 3.1.

-colorinterp_<X> {red|green|blue|alpha|gray|undefined|pan|coastal|rededge|nir|swir|mwir|lwir|...}

Change the color interpretation of band X (where X is a valid band number, starting at 1).

Added in version 2.3.

-gcp pixel <line> <easting> <northing> [<elevation>]

Add the indicated ground control point to the dataset. This option may be provided multiple times to provide a set of GCPs.

-unsetmd

Remove existing metadata (in the default metadata domain). Can be combined with -mo.

Added in version 2.0.

-mo <META-TAG>=<VALUE>

Passes a metadata key and value to set on the output dataset if possible. This metadata is added to the existing metadata items, unless -unsetmd is also specified.

-oo <NAME>=<VALUE>

Open option (format specific).

Added in version 2.0.
