This is a new type of animation I haven’t seen with Google Earth before. James Stafford has posted at his Barnabu blog a way to view hurricane satellite photo animations which doesn’t eat up too much memory. He creates “followspots” – just a circular clip around each hurricane – rather than animating the full-sized satellite photo. And uses the time slider feature in GE to allow you to watch animations. In the example provided (7 MBytes), he shows you several Atlantic hurricanes from 2006. If he had used the full-earth satellite photos for these animations it would have been >300 Mbytes, so this is a much more effective approach.
You can also watch a video of the animation here:
By the way, I’m headed to the Annapolis Boat Show for the next two days. I’ll have limited time for posting.
