Comment(by robe):

 sgottipamula -- do you have 2 geographies you can output in sql we can
 work with.
 Google earth doesn't quite follow spherical.  They use some tricks along
 the way so is still not proof there is an issue.  This is not to say there
 isn't but a picture isn't very actionalble anyway.

 We'll need a real set of geographies to work with to troubleshoot.  If its
 personal data, you can send to pramsey off list

 pramsey at cleverelephant.ca

 or me (lr at pcorp.us)  or both of us. pramsey would be better able to
 debug since he wrote a good chunk of the geography plumbing.
