The search giant said Wednesday it would start showing three-dimensional images for entire metropolitan areas in Google Earth. Up to this point, the service had shown 3-D images only of some buildings. Google said it would eventually also make the more-robust 3-D imagery available on Google Maps and to software developers.
In addition, Google said it would soon make Google Maps available on devices that run on its Android mobile operating system, even during times when the device doesn’t have an Internet connection because the user has poor wireless reception. Currently, the service works only if the device is connected to a wireless network.
