## Description

gdal vector edit can be used to edit metadata of a vector dataset: its CRS, the layer geometry type, dataset and layer metadata.

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

Features are not modified.

### 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.

--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.

--geometry-type <GEOMETRY-TYPE>

  Change the layer geometry type to be one of `GEOMETRY`, `POINT`, `LINESTRING`, `POLYGON`, `MULTIPOINT`, `MULTILINESTRING`, `MULTIPOLYGON`, `GEOMETRYCOLLECTION`, `CURVE`, `CIRCULARSTRING`, `COMPOUNDCURVE`, `SURFACE`, `CURVEPOLYGON`, `MULTICURVE`, `MULTISURFACE`, `POLYHEDRALSURFACE` or `TIN`. `Z`, `M` or `ZM` suffixes can be appended to the above values to indicate the dimensionality. Note that feature geometries themselves are not modified. Thus this option can be used to fix an inappropriate geometry type at the layer level.

--crs <CRS>

  Override CRS, without reprojecting.

  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.

  `null` or `none` can be specified to unset an existing CRS.

--metadata <KEY>=<VALUE>

  Add/update metadata item, at the dataset level.

--unset-metadata <KEY>

  Remove metadata item, at the dataset level.

--layer-metadata <KEY>=<VALUE>

  Add/update metadata item, at the layer level.

--unset-layer-metadata <KEY>

  Remove metadata item, at the layer level.

--unset-fid

  Added in version 3.12.

  Can be specified to prevent the name of the source FID column and source feature IDs from being reused for the target layer. This option can for example be useful if selecting source features with a ORDER BY clause.

### 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: Change the CRS of a GeoPackage file (without reprojecting it) and its geometry type

    $ gdal vector edit --crs=EPSG:4326 --geometry-type=POLYGONZM in.gpkg out.gpkg --overwrite
