Hi All,<br><br>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?<br>
<br>Thanks,<br><br>Roger<br>--<br><br><div class="gmail_quote">On Tue, Apr 14, 2009 at 4:23 PM, Roger André <span dir="ltr"><<a href="mailto:randre@gmail.com">randre@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

</div></div>v.generalize is available in GRASS >= 6.3.0. BTW, GRASS 6.2.3 is<br>
pretty old. Try the last RC of GRASS 6.4.0 (RC4).<br>
