METHODS AND SYSTEMS FOR OBTAINING LOCATION INFORMATION

摘要

A method involves dividing a geographic region represented by a digital map into a plurality of sub regions. An area code is assigned to each of the plurality of sub regions. A speed dial location code is assigned to each of a plurality of locations in each sub region. Each speed dial location code is associated with position information for the location to which it is assigned, and each speed dial location code is associated with the area code for the sub region which includes the location. A navigation apparatus determines the area code for a given sub region of interest, receives an input of a speed dial location code from a user, and obtains the position information associated with a speed dial location code which corresponds to the input speed dial location code, and which is also associated with the determined area code.
