EarthBrowser is now even faster and offers some new features including real-time satellites. An online API is just around the corner which will extend the application even further.
There are many schools which haven’t been able to install Google Earth across a network (mine included) and I view the two applications as being broadly complementary. Google Earth is great for spatial decision-making that requires high resolution imagery, while EarthBrowser is a better alternative when using global data sets such as webcams, volcanoes earthquakes and storms – which are all available within a single click from the main screen, as opposed to the increasingly complex Layers within Google Earth.
If you haven’t looked at EarthBrowser recently, do give it a try. It’s a free, super-fast download, and a site license is available.
