Google Earth 7.0 has been released, introducing 3D maps for a selection of major cities around the world. Based upon 3D telemetry and textures taken from aerial photography, Earth 7.0 conjures a virtual city right onto your smartphone or tablet screen. What this means is you can now fire up Google Earth and zoom around any of the supported cities, which include San Francisco, Boston, Charlotte and Rome. There's also a dedicated tour mode which will give you a virtual fly-by view of major landmarks, including the Transamerica Pyramid in San Francisco.

As you might expect, the new 3D mapping capabilities require a fair amount of graphical power and bandwidth to use, though we demo'd the new Google Earth on the 18-month-old Motorola Xoom, and the app remained fairly smooth and speedy.

Check out our hands-on video above. Google Earth 7.0 is available to download now from the Google Play Store. For 3D building support, you'll need to be running Android 4.0 Ice Cream Sandwich or later.
