Hi.<br>I tried to use the ellipse function in<br>http://postgis.refractions.net/support/wiki/index.php?plpgsqlfunctions<br><br>but i find a problem.<br>The shape of ellipse depends on the latitude of the center point (the ry variable).<br>The bigger is it, the more the ellipse is stretched.<br>How can i solve this problem?<br>Thanks a lot.<br><br><p>
