Hi, Chris —
<div>Please see <a href="http://cola.gmu.edu/grads/gadoc/shapefiles.html#caveat">http://cola.gmu.edu/grads/gadoc/shapefiles.html#caveat</a></div>
<div>GrADS doesn’t handle drawing polygons with holes, so it doesn’t create them that way either. The vertical lines are an artifact of cutting the donuts in pieces in order to eliminate the holes. You have to draw them filled and outlined with the same color
— then you cannot see those vertical lines and the shaded contours look normal.</div>

<p class="MsoNormal">I’m having some issues producing KML output (with polygon option; grads version 2.1.a3). I’m trying to specify my own values for the polygons, but unfortunately the output is always for different values to the one that I specify. For example:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">‘define east=ugrdl125’<o:p></o:p></p>
