Back to the Google Earth time animations I put together in [Post 028]. In this one I’ve kept the time animation sequence from the race and added an image (ground) overlay over Hawaii.

Google Earth has a fantastic set of tools to precisely position and stretch/ compress images to get the right fit once the overlay is run. Then its just a case of getting the lat long bounding box co-ordinates to reference along with the image in the ground overlay KML tags.
Here it is:
