<DIV>my codes is from the <A href="http://mapguide.osgeo.org/livegallery.html">http://mapguide.osgeo.org/livegallery.html</A> and I want to do the same thing as <A href="http://data.mapguide.com/mapguide/DynamicKml/GoogleEarth.php">http://data.mapguide.com/mapguide/DynamicKml/GoogleEarth.php</A> Ｉjust used their codes and use my data instead,but I can't get the right result.</DIV>
<DIV>If there is no BBOX,can I get the Geometry?</DIV>
<DIV>the file which invoke that function is just as follows.</DIV>
