Hi all!<br><br>I am confused about the utility of r.patch and i.group w.r.t. image classification.<br><br>In ERDAS for supervised classification layer stacking can be done followed by classification.<br><br>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?<br>
<br>Thanks and regards,<br><br>Chethan S.<br clear="all"><br>
