DESCRIPTION

gdal vector geom swap-xy swaps the X and Y coordinates of geometries, typically to work around axis order issues of coordinate reference systems.

It can also be used as a step of gdal vector pipeline.

Standard options

-f, --of, --format, --output-format <OUTPUT-FORMAT>: Which output vector format to use. Allowed values may be given by gdal --formats | grep vector | grep rw | sort

--co <NAME>=<VALUE>

Many formats have one or more optional dataset creation options that can be used to control particulars about the file created. For instance, the GeoPackage driver supports creation options to control the version.

May be repeated.

The dataset 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 Vector drivers format specific documentation for legal creation options for each format.

Note that dataset creation options are different from layer creation options.

-lco <NAME>=<VALUE>: Layer creation option (format specific)

--overwrite: Allow program to overwrite existing target file or dataset. Otherwise, by default, gdal errors out if the target file or dataset already exists.

--active-layer <ACTIVE-LAYER>: Set the active layer. When it is specified, only the layer specified by its name will be subject to the processing. Other layers will be not modified. If this option is not specified, all layers will be subject to the processing.

--active-geometry <ACTIVE-GEOMETRY>: Set the active geometry field from its name. When it is specified, only the specified geometry field will be subject to the processing. Other geometry fields will be not modified. If this option is not specified, all geometry fields will be subject to the processing. This option can be combined together with --active-layer.

Advanced options

--oo <NAME>=<VALUE>: Dataset open option (format specific).
May be repeated.

--if <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 several 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.

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 vector dataset using the GDALG: GDAL Streamed Algorithm driver, and apply the specified pipeline in a on-the-fly / streamed way.

EXAMPLES

Example 1: Basic usage

$ gdal vector geom swap-xy in.gpkg out.gpkg --overwrite
