NAME
gdalmove - Transform georeferencing of raster file in place.
SYNOPSIS
gdalmove.py [-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 val-
ues at all. It is loosely similar to using gdalwarp to transform an im-
age 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 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.
-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.
