Multiple regions/signature in i.class

[IBH7CAB at MVS.OAC.UCLA.EDU]

Michael,

I thought about defining multiple regions for a class, e.g.,
forest1, forest2, forest3, plotting the centroids for each
cluster, then seeing whether it makes sense to combine all or
any of these with i.reclass.  My problem is that some of my
regions will consist of small gardens with only 8-12 pixels...
thus my interest in defining multiple regions for a class.
Thanks for your suggestion.
