I just downloaded Google Earth and so far it seems pretty nice. It takes advantage of both the Accelerometer and the GPS in the iPhone 3G. It is stunning. Tilting the iPhone allows you to move through the terrain and works pretty well. The GPS allows you to find your current location and see the Panoramio geolocations around you. And although not a replacement for Google Maps because you can’t see the street names, it is pretty cool.
Here is what the Google Blog had to say:
Even before we introduced Google Earth back in 2005, the team had long dreamed of being able to carry the Earth around in your pocket. Well, today that dream becomes a reality as we introduce Google Earth for iPhone and iPod touch. With just a swipe of your finger you can fly from Peoria to Paris to Papua New Guinea, or anywhere in between. It may be small, but it brings all the power of Google Earth to the palm of your hand, including all of the same global imagery and 3D terrain. You can even browse any of our 8 million Panoramio photos or read Wikipedia articles.
With Google Earth for iPhone, you can:
• Tilt your iPhone to adjust your view to see mountainous terrain
• View the Panoramio layer and browse the millions of geo-located photos from around the world
• View geo-located Wikipedia articles
• Use the ‘Location’ feature to fly to your current location
• Search for cities, places and business around the globe with Google Local Search
