Hi,
while searching for the new i.class tool I have discovered
the "supervised classification tool"
in Imagery -> Classify Image -> Interactive input for supervised classification
Nice! /edit: I now see that it *is* the

I tried it with NC data and loaded the Landsat2002 group.
Now I would expect that I can select channels for display from
the group. Perhaps something with [x] checkboxes would be
good. The existing "free" choice of maps should remain of course.
When I then digitize, it nicely opens the class dialog, ok. Then,
when running, it segfaults (entire wxGUI disappears, no error msg
visible).
Suggestion: It may also become the tool for i.smap, just a method
dialog would be needed
> Run Analysis
- MaxLik: i.maxlik
- SMAP: i.gensigset, i.smap
to make it universal. However, great to have such a tool now.
