<div dir="ltr"><div><div>Hi Markus, <br><br></div>Thanks for your reply. Actually,I investigated a bit more and I realized that this is probably because of GRASS topological model.<br><br></div><div>As you can see, some of my generated polygons overlaps others - and some centroids may be contained into others polygons (on same vector map). I guess, GRASS doesn't like much this situation (could you confirm ?).</div><div><br></div><div>Anyway, any precision would be appreciated to understand better.<br><br></div><div><br></div><div>If you still think it could be a bug. I'll find time for reporting it. Thanks again.</div><div><br><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Jun 7, 2015 at 10:38 PM, Markus Neteler [via OSGeo.org] <span dir="ltr"><<a href="/user/SendEmail.jtp?type=node&node=5209706&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>></span> wrote:<br><blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">

<br><br>While I am not sure if this a bug, please open a ticket for it along
