James Stafford has posted another flight visualization collection for Google Earth which uses a really cool KML technique. This time he shows the US domestic flight routes from an FAA database for October 2007 (over 13,000 flights). After loading his file (2MB), when you move your mouse over a placemarks for an airport it immediately shows flight lines from that airport to destinations within the US. If you click and hold your middle mouse button on a placemark you can pan and tilt your view and see how the lines connecting airports are represented by nice parabolas. If you have a SpaceNavigator 3D mouse, you can really zoom around and get a look. To show off this file and these techniques, I’ve made a short little video clip:
James said he was concerned how GE would perform with over 13,000 flights represented. But, GE seems to handle them well. Read more at James’ Barnabu blog.
