Google announced Google Maps 5.0 for Android, the latest version of the company’s mapping app for Android handsets. The first new feature enables users to explore Google Maps in 3D. By dragging two fingers down the screen of their Android handsets, users can tilt a city map and see the skyline changed into 3D form. Next step, users can rotate an individual building to see it from different angles. Zooming is also smoother in this latest version of Google Maps, according to the company. Maps can also be centred on a user’s individual location and then, by tapping the compass button, the map will go into 3D mode so matching the individual user’s perspective.

The second feature is intended to offer greater offline reliability which means “you can find your way even if you lose your connection”, according to Michael Siliski, a Google product manager writing on the company’s mobile blog. The tactic is to cache the relevant data for users based on their individual travel routes. In the case of a lost connection, the cached data will fill the gap for users. “This way, you can rely on having fast, robust maps available to you where you’re most likely to need them,” says Siliski. Google Maps will automatically start caching the areas users visit most when their Android handset is plugged in and connected to Wi-Fi (generally overnight charging).

Finally, Siliski points to a new addition to the Google Maps Navigation beta, the company’s turn-by-turn GPS navigation service, This addition is intended to get users back on track rapidly if their Internet connection is broken when using the service.

Google says the new features all take advantage of “dynamic map drawing technology” that makes mapping more data efficient. “We estimate that viewing maps now requires almost 70% less mobile network data overall than before,” says Siliski. Google Maps 5.0 for Android is now available for downlaod in the Android Market.
