<pre style="white-space: pre-wrap; word-wrap:break-word; font-family: sans-serif; margin-top: 0px"> I have a map of streams and rivers that is about 474M for the coor file<br />and 65M for the topo file; very large. The area of interest is very much<br />smaller and I tried using v.overlay with the 'and' (intersect) operator to<br />clip the huge line map with the small area map. After about 1/2-hour of<br />processing the system shut down because the CPU overheated (at it's only 20C<br />here today).<br /><br />Are there other modules, or ways of using v.overlay, that will allow me to<br />trim off smaller chunks of the line file?<br /><br />TIA,<br /><br />Rich<br /><br /><hr /><br />grass-user mailing list<br />grass-user@lists.osgeo.org<br /><a href="http://lists.osgeo.org/mailman/listinfo/grass-user">http://lists.osgeo.org/mailman/listinfo/grass-user</a><br /></pre></blockquote></div><br>
