Abstract
Digital mapping techniques are disclosed that provide more flexibility to the user through the use of multiple views of map information, including a secondary map and a main map. The secondary map can provide the user with either a zoomed out or in relative to the main map, or a different type of map view (e.g., satellite images). The secondary map can be turned on and off by the user. The secondary map may include one or more viewing frames that indicate views (e.g., current and alternate views) of the main map. The user can move the main map, viewing frame, or secondary map to achieve desired map views. During such movement, the relationship between the main and secondary maps can be synchronous, partially synchronous, or serial.
