Google Maps 5 for Android comes with two features that make Google's mapping software a lot more useful. Google now uses vector graphics instead of map tiles and it caches some of your most frequently used maps so that they are available offline.
Vector-based maps allowed Google to add a lot of cool gestures:
Tilting: Drag down with two fingers to tilt the map. Tilt while zoomed in on one of the 100+ cities around the world with 3D buildings to see a skyline spring to life.
Rotating: Twist with two fingers to rotate the map. After tilting to see 3D buildings, rotate around them to gain a new perspective from any direction.
Smooth zooming: Slide two fingers together or apart, and see the map and labels continuously scale to any zoom level, stopping when your fingers stop.
Compass mode: Center the map on your location, and then tap the compass button in the top right corner. The map will flip into 3D mode and start rotating to match your perspective, while still keeping all the labels upright and readable.
