FWIW, I've added a -c flag to r.neighbors to use a circular neighborhood rather than a square. I'm unsure as to whether the test should be < or <=. It's currently <=, but that gives "spikes" (single cells) at the four edges. Using < would give "flats", and would always omit the outermost row/column of pixels. Maybe there should be a +0.5 in the distance calculation? -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
