Google’s Google Earth version for iPhone  launched on this Sunday, on the Apple’s App store as a free software. 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. The iPhone version of Google Earth produces images on the maps by dotting the map with landmarks, photos, and other information.

The view of the terrain looks straight down you can tilt the view so terrain contours are visible, and generating that variable perspective.The iPhone version of the Google Earth is more easier with the Two-finger pinch gestures.Dragging a fingertip across the screen slides to view screens appropriately.

The software makes use of the iPhone’s accelerometer and adjusts your view accordingly, when the iPhone is tilted at a certain angle, so that you can look up into the sky. And it’s also integrated with the iPhone’s ability to locate itself through GPS, Wi-Fi networks, and mobile phone towers.

Peter Birch, Google Earth’s product manager Said,

“The idea of having Earth on a mobile device is something people dreamed of back to the Keyhole days and before,”
