<div class="moz-cite-prefix">Hi, maybe you can identify your closed
lines with v.to.db command and the coordinate of the start point

<pre style="color: rgb(0, 0, 0); font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">v.to.db map=mylines option=end type=line col=coordEnd
v.to.db map=mylines option=start type=line col=coordStart
</pre>
<br>
and tests if the coordinates of the startNode and the EndNode are
equals, the line is closed and you can tag your lines .<br>
And use after the v.extract command to extract only the lines
which are not closed.<br>
<br>
Hope it can be helpful<br>

Hi,
I would like to know how to remove automatically small circles (closed lines, not area). I've tried with v.clean and v.generalize but I just get to remove line which are not closed.
Regards
Lucien</pre>
