<p>Hello Vero,<o:p></o:p></p>
<p>Thanks for your reply. It took almost one hour to extract my
area (I guess because of topology). I do the same with Qgis
from a shape in less than 10 minutes (but with several
operations)... it's may be a bad idea to have a so heavy
vector map in Grass...
<o:p></o:p></p>
<p>Cheers,<o:p></o:p></p>
<p>Frank<o:p></o:p></p>

<p class="MsoNormal">Hello,<br>
<br>
What is the best and fast way to make a copy of a part
of vector map <br>
(national) to get a smaller territory ? (partial copy).<br>
Thank you for your advice !<br>

Frank<br>
