gdalmove(1)gdalmove(1)NAMEgdalmove - 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
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.
-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.
