Brad,
I haven't used the module, so I can't say. The reason for making it
*possible* to run non-interactively (even if it *can* be run interactively
if desired) is that it can then be wrapped into a non-x11 GUI. As long as
interactive terminal input is required, this is not possible.
Excellent point. I hadn't considered alternative GUIs.
There is no problem running the module twice in different modes to have it
compute transform coordinates, so long as those coordinates can be output to
stdout or a file that could be subsequently used by the module running in
different mode. On the other hand, if this involves interactively clicking
on photo reference points and a georeferenced map to create a file of point
pairs (photo/image and georeferenced equivalents), there should be the
option of replacing this task by GUI code. For example, the TclTk
georectifier integrates i.group, i.target, and i.rectify. However, the
interactive i.points is simply replaced by TclTk code that generates a POINT
file used by i.rectify.
Right now, coordinates are stored in the REF file. I assume the same is
true for i.points/i.rectify, but haven't reviewed that code, yet.
I'm not sure if this is helpful to you or not. However, to incorporate this
into a current or new GUI, there needs to be some way to run this module or
its decendent(s) 100% non-interactively.
Yes, this has been helpful.
