The georef Command
The georef command, that can have no 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;
- the
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.
