<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>Just a couple more comments about the TclTk georectify module.<BR>
<BR>
It is a TclTk replacement for i.points and i.vpoints, combined with integrated interface to i.group, i.target, and i.rectify. There has been some discussion about dropping i.rectify for gdalwarp. I’ve used i.rectify here, but it is probably possible to rewrite this to use gdalwarp in the future.<BR>
<BR>
Because it uses a TclTk canvas and replaces i.points and i.vpoints, it does not require x11 for interactive selection of ground control points from georectified and non-rectified maps.<BR>
<BR>
Finally, I want to acknowledge some critical help from Glynn Clements for ideas of how to get the map points into the GCP manager window.<BR>
