NAME

       gdalmove - Transform georeferencing of raster file in place.

SYNOPSIS

          gdalmove.py [--help] [--help-general]
                      [-s_srs <srs_defn>] -t_srs <srs_defn>
                      [-et <max_pixel_err>] <target_file>

DESCRIPTION

       The  gdalmove.py  script transforms the bounds of a raster file from one coordinate system
       to another, and then updates the coordinate system and geotransform of the file.  This  is
       done  without  altering  pixel  values  at all. It is loosely similar to using gdalwarp to
       transform an image but avoiding the resampling step in order to avoid image damage. It  is
       generally only suitable for transformations that are effectively linear in the area of the
       file.

       If no error threshold value (-et) is provided then the file is not actually  updated,  but
       the  errors  that would be incurred are reported. If -et is provided then the file is only
       modify if the apparent error being introduced is less  than  the  indicate  threshold  (in
       pixels).

       Currently  the transformed geotransform is computed based on the transformation of the top
       left, top right, and bottom left corners. A reduced overall error could be produced  using
       a least squares fit of at least all four corner points.

       --help Show this help message and exit

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

       -s_srs <srs_defn>
              Override  the  coordinate  system  of the file with the indicated coordinate system
              definition. Optional. If not provided the source coordinate system is read from the
              source file.

       -t_srs <srs_defn>
              Defines the target coordinate system. This coordinate system will be written to the
              file after an update.

       -et <max_pixel_err>
              The error threshold (in pixels) beyond which the file will not be updated.  If  not
              provided no update will be applied to the file, but errors will be reported.

       <target_file>
          The file to be operated on. To update this must be a file format that supports in place
          updates of the geotransform and SRS.
