I'm using 1st order and 13 GCPs on an image and i.rectify has been running
over 3 hours. Is the process locking up or is this amount of time normal
in image rectification? Is i.rectify processing just the area of the
image to be rectified, of is it calculating for the whole target mapset
area? In other words, should I have applied a mask to the target mapset
before running the georectify tool in order to cut down on processing
time?
Any info would be greatly appreciated.
Thanks!
