The 3rd edition GRASS book is really the way to go, perhaps after what Werner recommended. It is one of the best books I have read on GIS as it relates to concept and actual usage and implementation. It has lots of applicable examples. I cant recommend it enough. http://www.grassbook.org/

Thank you Hamish...your set of commands worked great! It still bothers me that r.to.vect would produce invalid topology. Btw, I also tried to use v.generalize but my vectyor seem to lose its attribute table. -Original Message- From: Hamish [mailto:hamis...@yahoo.com] Sent: Friday,

Upon closer inspection, I see what you are talking about. I do want to remove holes = 2800 m, so this method won't work for me. So, what would cause r.to.vect to create areas without centroids? And why haven't v.clean rmarea filled all of my holes since they all don't have centroids?
