Hi Glynn, I was just looking at the CVS version of r.neighbors but didn't see where I can specify use an arbitrary neighbourhood shape unless it has something to do with the weight=string option. Unfortunately the documentation doesn't mention how to use it.
So, with r.neighbors, how would I annulus shape neighbourhood shape? Thanks for your help!

The current CVS version of r.neighbors allows the use of an arbitrary neighbourhood shape, as well as per-neighbor weights. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
