Google has just released the first iPad version of its Google Earth app, which is available now to download for free from the Apple iTunes App Store. You can use the app in the same way as you would the desktop version, with the added bonus of being able to navigate the globe by swiping your finger across the touch screen, or use two fingers to adjust your viewpoint so that you see mountainous terrain. You can also, among many other things, view layers of geographic information including roads, borders and Panoramio photos, search using voice commands in English, Mandarin or Japanese, jump straight to your current location at the touch of a button, and view geo-located Wikipedia articles.
As you might expect, the main addition to the iPad version is the full-resolution imagery and the iPad-specific look and feel. A road layer has also been added for iPad and iPhone 3GS.
