Rising Sea Levels – Using a simple technique of wrapping the world with a sea-level sphere and scaling it bigger meter by meter, ‘Bzoltan‘ (a member of the GE Community from Hungary) has posted a time animation illustrating what might happen if sea levels rose from 1 to 100 meters. Given concerns about global warming, it seems appropriate to be thinking about the effects of sea level. Load the GE file here – it will default to a view over San Francisco. Hit the “Play” button on the time slider (a triangular right-arrow to the right of the slider) to start the animation. Or, just grab the slider and slide it back and forth to see the effects. Check out other coastal cities around the world like New York, Sydney, Tokyo, Hong Kong, etc. On a related note, Noel Jenkins at DigitalGeography has an educational lesson on rising sea levels using similar techniques (but, without the time animation).
Filling Grand Canyon – In a similar fashion, Bzoltan also created an animation showing what it would look like to fill up the Grand Canyon. Given the complex 3D terrain, and the familiarity of the size of the Grand Canyon, this animation seems even more dramatic.
Global Clouds Animation – One of my favorite add-ons for Google Earth has always been the addition of current global clouds. I like it even better when combined with the NASA Blue Marble add-on (which includes the clouds in the same package). One of the more innovative 3D modelers, who calls himself ‘barnabu‘ at the GEC, has produced an updating global clouds animation that shows the clouds for the last 10 days. Load the file , and then start the time animation (NOTE: the first time through it has to load the images – 5 MBytes). Very cool animation! ‘barnabu’ now has a web site dedicated to highlighting his interesting Google Earth creations. You can also see the review of his London Eye animation (and a list of other reviews I’ve done of his works).
