automated testing with Google Maps API

Thank you David.  I have briefly reviewed the Region Checkpoint information.   As I understand it, this will let me compare images with previously captured images.   I am thinking that this pretty much limits me to a 'catch and replay' situation.  That is, I'll be able to check that icons on the map show up the same way they were last time. Ideally, I'd like to be able to  identify what icons and which icons have been dropped, and access the icons at least to click on them .   I've attached a screen shot.
