<DIV>Hi Guy,</DIV>
<DIV>I know that i'm not the only one who have TopologyException probelm.</DIV>
<DIV>But the folowing exemple was running well in previous version (before geos 2.1.4) and return POINT(0.1,0.1) :</DIV>
<DIV> </DIV>
<DIV>select<BR>astext(intersection(geomfromtext('POLYGON ((0 0, 0 0.5, 0.1 0.5, 0.1 0.1, 0 0))', 27582), <BR>geomfromtext('POLYGON ((0.5 0, 0.1 0, 0.1 0.1, 0.5 0.5, 0.5 0))', 27582)))</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I've chechek the validity of the two geom, and i try also</DIV>
<DIV> </DIV>
<DIV>select <BR>astext(intersection(ForceRHR(geomfromtext('POLYGON ((0 0, 0 0.5, 0.1 0.5, 0.1 0.1, 0 0))', 27582)), <BR>ForceRHR(geomfromtext('POLYGON ((0.5 0, 0.1 0, 0.1 0.1, 0.5 0.5, 0.5 0))', 27582))))</DIV>
<DIV> </DIV>
<DIV>Is there a way to work around this pb ? </DIV>
<DIV>Does news geos 3.0.0 rc1 and the new binaryOp solve this ?</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV>Pierre</DIV></DIV><BR>
