## Description

gdal vector convert can be used to convert data data between different formats.

The following options are available:

### 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.

--layer-creation-option <NAME>=<VALUE>

  Many formats have one or more optional layer creation options that can be used to control particulars about the layer created. For instance, the GeoPackage driver supports layer creation options to control the feature identifier or geometry column name, setting the identifier or description, etc.

  May be repeated.

  The layer creation options available vary by format driver, and some simple formats have no layer 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 layer creation options are different from dataset creation options.

--overwrite

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

--update

  Whether the output dataset must be opened in update mode. Implies that it already exists. This mode is useful when adding new layer(s) to an already existing dataset.

--overwrite-layer

  Whether overwriting existing layer(s) is allowed.

--append

  Whether appending features to existing layer(s) is allowed

-l, --layer <LAYER>

  Name of one or more layers to inspect. If no layer names are passed, then all layers will be selected.

--output-layer <OUTPUT-LAYER>

  Output layer name. Can only be used to rename a layer, if there is a single input 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.

## Examples

### Example 1: Converting file `poly.shp` to a GeoPackage

    $ gdal vector convert poly.shp output.gpkg

### Example 2: Add new layer from file `line.shp` to an existing GeoPackage, and rename it "lines"

    $ gdal vector convert --update --output-layer=lines line.shp output.gpkg

### Example 3: Append features from from file `poly2.shp` to an existing layer `poly` of a GeoPackage, with progress bar

    $ gdal vector convert --append --output-layer=poly --progress poly2.shp output.gpkg
