Google Earth lets people virtually fly around a 3D view of the world made from satellite and aerial imagery mapped onto the planet’s mountains and valleys. Google releases its updated Google Earth 3.0 version for iPhone. The iPhone version reproduces amazing experience, downloading imagery from Google’s servers as the perspective shifts and dotting the map with landmarks, photos, and other information. It is a must have iPhone app.
iPhone’s multitouch screen actually made using the application easy. Dragging a fingertip across the screen slides the view appropriately, of course. Two-finger pinch gestures not only zoom in and out, but also, by adding a little twirling rotary motion, steer the view’s orientation in one direction or another. When the iPhone is tilted a certain angle out of horizontal, Google Earth reads data from the phone’s accelerometer and adjusts your view accordingly, so you can look up into the sky. And it’s integrated with the iPhone’s capability to locate itself through GPS, Wi-Fi networks, and mobile phone towers.
