| | | The georef Command |
The georef command, that cannot have options, writes to the standard output a GPSMan map information file containing geo-referencing information for an image:
georef IMGPATH TRANSF LATD LONGD LATD LONGD [LATD LONGD] DATUM \
X Y X Y [X Y] PROJECTION [PARAMS]
where:
IMGPATH is the path to the image file;
TRANSF is the coordinates transformation to use; the
command show transfs produces a list of
the available transformations;
LATD LONGD pairs and DATUM are the latitude
and longitude in signed decimal degrees and the datum of the
2 or 3 control points whose pixel coordinates are the
X Y pairs in the same order; the origin of the pixel
coordinates is the top left corner of the image and the
y-coordinates increase downwards;
PROJECTION [PARAMS] defines the projection and
its parameters; if no datum=X parameter is given the datum
of the points is used; the command show
projections gives a list of the available projections
and their parameters.
