METHOD FOR UPDATING THE TERMINAL'S MAP INFORMATION BASED ON ROUTE AREA AND SERVER THEREFOR

摘要

A method and a server for updating map information of a terminal based on a search route is provided to offer the updated map information to the terminal by searching a route from a starting place to an arrival place, extracting the map information corresponding to the searched route, and transmitting the extracted map information to the terminal. A storing part stores a map version and map data of each unit area, and keeps the map data of an updated version. A communicator receives route information, route search mode information, and terminal map version information from a terminal, and transmits the extracted map data to the terminal. A route searcher(12) searches the route on the map data stored in the storing part by using the route information and the route search mode information. A map version manager(13) checks a difference between the map version of the map data stored in the terminal and the storing part by each area along the searched route. An updated area extractor(14) extracts and transfers the unit area map data corresponding to the map version checked in the map version checker to the communicator.
