In some embodiments, the mapping application provides a smart zoom feature that guides a user during a zoom to a location. In particular, the smart zoom detects that a location of a zoom is near a pin on the map, and if so, zooms to the pin on the map. Otherwise, if the location is near a cloud of pins, the application zooms to the cloud of pins. Otherwise the zoom is directed towards the user's selected location. | 12-11-2014 |
