[GRASS-user] i.group and r.patch in supervised classification

[Chethan S.]

Hi all!

I am confused about the utility of r.patch and i.group w.r.t. image
classification.

In ERDAS for supervised classification layer stacking can be done followed
by classification.

A way to layer stack in GRASS would be r.patch (since layers are more than
3, I can't use r.composite). But for classifying in GRASS since i.group has
to be used, can I use i.group to do layer stacking instead of using r.patch
and then classify?

Thanks and regards,

Chethan S.
