Hi All, Got Version 6.4 working last night and started to experiment with v.generalize. I'm using it on a group of polygons that represent the Hawaiian islands and noticed some interesting behavior. In other systems, I would expect these features to be treated at "multipolygons", however in GRASS I see that I have the option of specifying point, line, boundary, or area. I'm not exactly sure what the difference between boundary and area is, but it does seem to make a difference in the v.generalize output which of them I choose. Can someone clarify for me how these geometry types affect the operation v.generalize?
