Google has released Google Maps for Android and has made major modifications to how maps are rendered. This is major update with some really interesting new features. Google is really paying attention to the needs of mobile users and making Google Maps for Android one of the premier apps for their mobile OS.
Some of the new features include:
1) Vector maps: Maps now uses vectors to draw maps instead of bitmap images. This allows for easier zooming, rotation and markup.
2) You can now use a compass mode to have the map rotate as you change directions. Labels will also be redrawn to face you.
3) 3D buildings are now displayed when available for increased realism.
4) Better offline capabilities: With the change to vector formats, it is now possible to perform limited zooms in and out without having network connectivity. This updated version will also pro-actively cache some detailed views around your frequent places so that you have access even if you connectivity is unreliable.
