My main point was you have two columns "geometry" and "Coordinates".
In row 1 for example, geometry contains:
<Point><coordinates>-118.246208,33.923831,0.0</coordinates></Point>
Coordinates contains:
33.923831,-118.246208
You need to extract those coordinates (latitude=33.923831,
longitude=-118.246208), use them to create a google.maps.LatLng
object, then use that as the argument to a call to map.setCenter().
It would be simpler to use the Coordinates column (just do a
String.split(",")), but you can parse it out of the kml. I thought I
saw an example posted to the group that did that, you could try
searching for it (or maybe someone else can point to that reference, I
can't find it right now)
