## Description

gdal vector reproject can be used to reproject a vector dataset. The program can reproject to any supported projection.

This command 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.

--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.

-s, --src-crs <SRC-CRS>

  Set source spatial reference. If not specified the SRS found in the input dataset will be used.

  The coordinate reference systems that can be passed are anything supported by the OGRSpatialReference.SetFromUserInput() call, which includes EPSG Projected, Geographic or Compound CRS (i.e. EPSG:4296), a well known text (WKT) CRS definition, PROJ.4 declarations, or the name of a .prj file containing a WKT CRS definition.

  If the SRS has an explicit vertical datum that points to a PROJ.4 geoidgrids, and the input dataset is a single band dataset, a vertical correction will be applied to the values of the dataset.

-d, --dst-crs <SRC-CRS>

  Set destination spatial reference.

  The coordinate reference systems that can be passed are anything supported by the OGRSpatialReference.SetFromUserInput() call, which includes EPSG Projected, Geographic or Compound CRS (i.e. EPSG:4296), a well known text (WKT) CRS definition, PROJ.4 declarations, or the name of a .prj file containing a WKT CRS definition.

  If the SRS has an explicit vertical datum that points to a PROJ.4 geoidgrids, and the input dataset is a single band dataset, a vertical correction will be applied to the values of the dataset.

## 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: Reproject a GeoPackage file to CRS EPSG:32632 ("WGS 84 / UTM zone 32N")

    $ gdal vector reproject --dst-crs=EPSG:32632 in.gpkg out.gpkg --overwrite
