Method of establishing Map Data and Navigation Device
First Claim
1. A method of establishing map data for a navigation device, the navigation device comprising a position device for receiving a plurality of satellite signals to obtain a plurality of coordinates of the navigation device, a user interface for receiving a command inputted by a user, a map database for storing map data, and a navigation processor coupled to the user interface, the position device and the map database for outputting a comparison result according to the command, the coordinates and the map data, the method comprising:
- recording the plurality of coordinates of the position device;
comparing the plurality of coordinates with the map data to generate the comparison result; and
determining whether to update or establish new map data according to the command.
