NAME
       gdalmove	- Transform georeferencing of raster file in place.

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

DESCRIPTION
       The gdalmove script transforms the bounds of a raster file from one co-
       ordinate	 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 gen-
       erally 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 ac-
       tually updated, but the errors that would be incurred are reported.  If
       -et  is provided	then the file is only modify if	the apparent error be-
       ing introduced is less than the indicate	threshold (in pixels).

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

       NOTE:
	  gdalmove  is	a Python utility, and is only available	if GDAL	Python
	  bindings are available.

       --help Show this	help message and exit

       --help-general
	      Gives a brief usage message for the generic GDAL commandline op-
	      tions 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.
