DESCRIPTION

The gdal_edit.py script can be used to edit in place various information of an existing GDAL dataset (projection, geotransform, nodata, metadata).

It works only with raster formats that support update access to existing datasets.

--help-general:
    Gives a brief usage message for the generic GDAL commandline options and exit.

-ro:
    (GDAL >= 1.11) 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.

-a_ullr ulx uly lrx lry:
    Assign/override the georeferenced bounds of the dataset.

-tr xres yres :
    Set target resolution. The values must be expressed in georeferenced units. Both must be positive values.

-unsetgt:
    Remove the georeference information.

-unsetstats:
    (GDAL >= 2.0) Remove band statistics information.

-stats:
    (GDAL >= 2.0) Calculate and store band statistics.

-approx_stats:
    (GDAL >= 2.0) Calculate and store approximate band statistics.

-a_nodata value:
    Assign a specified nodata value to output bands.

-unsetnodata:
    (GDAL >= 2.1) Remove existing nodata values.

-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:
    (GDAL >= 2.0) Remove existing metadata (in the default metadata domain). Can be combined with -mo.

-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':
    (GDAL >= 2.0) Open option (format specific).

-a_ullr, -tr and -unsetgt options are exclusive.

-unsetstats and either -stats or -approx_stats options are exclusive.

EXAMPLE

gdal_edit -mo DATUM=WGS84 -mo PROJ=GEODETIC -a_ullr 7 47 8 46 test.ecw
