Google Earth Gets an Update

Google has upgraded one of its flashier products, the Google Earth mapping application, with a revamped user interface and a larger index of images, the Mountain View, California, company said yesterday.

Google Earth is one of the company's most successful products, garnering acclaim from users and industry observers alike. There have been more than 100 million unique downloads of the application in the past year.

The free, downloadable application taps into a multi-terabyte database of satellite images and, with a video-game-like interface, lets users travel around the world, virtually flying from destination to destination and zooming in and out of cities.

Google acquired the software in 2004 when it bought Keyhole. The Google Earth product family also includes more advanced, fee-based versions of the free application designed for commercial uses.

On Monday, Google announced that Google Earth's index of high-resolution satellite and aerial imagery has been quadrupled. Google Maps, the online mapping service, will begin tapping into this expanded index soon. This, in turn, will benefit the Google Local business-listings search service with which Google Maps is tightly integrated.

Meanwhile, the more streamlined user interface includes new tools to create and display content generated by users and external applications. This is a nod to the now popular practice among Internet companies of encouraging users and external developers to extend their services and products with contributions such as plug-ins, applications, tags and reviews.

Additional Improvements

For the first time, Google Earth is now available for the Linux operating system, in addition to Windows and Mac OS. And it now comes in Spanish, Italian, German, and French versions.

Also new in Google Earth is support for the creation of textured building drawings with the Google SketchUp application for creating, viewing and modifying 3D images.

Lastly, Google has updated its Google Maps application programming interface (API) to tie address data into applications that use Google Maps. Meanwhile, Google also unveiled a fee-based license for businesses interested in tapping Google Maps for Web or internal applications.

The Google Earth upgrade, version 4 of the application, is being released in beta, or test, form, at earth.google.com.
