As shown in the first line, the validation of the projected coordinate system suc-
ceeded. In this case, the underlying geographic coordinate system is EPSG:4258 (a
different spheroid was used). The projected coordinate system is based on a Lambert
Azimuthal Equal Area EPSG:9001, with its center at in central Europe (longitude
10
ⓦ
and latitude 52
ⓦ
). The false easting and northing parameters are offsets to ensure
all coordinates within the area of interest (Europe) are positive.
8.8 gdalmove.py
With
gdalmove.py
you can transform the coordinate system and geotransform of
a file without actually changing the pixel values. The geotransform of an image is
the set of six coefficients that define the affine transformation of a pixel and line in an
image coordinate system and X Y in a projected coordinate system. Approximating
the coordinate system transformation by an affine transformation introduces an error
that is evaluated by the command. If the error is above a threshold (defined by the
option
-et
), the file is not updated. The default value of the threshold is 0, thus not
setting the option will not alter the file. The error values for the corner coordinates
are reported both in the projected and image coordinate systems.
Usage: gdalmove.py [-s_srs <srs_defn>] -t_srs <srs_defn> [-et
ₒ
<max_pixel_err>] target_file
-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.
