Abstract
The telematics service providing system generates a path from the departure point to the destination based on traffic information, generates guidance information for each guidance point where a turn to a direction that is different from the current progress direction of the client is needed on the generated path, clips a vicinity map covering a predetermined area with reference to the guidance point from the total map to generate a guidance point vicinity map, converts the generated guidance point vicinity map into a format displayable by the client, and provides the converted map to the client terminal. Accordingly, confusion caused by complex crossroads or paths that need consecutive and same direction turns may be prevented, the client terminal may not need a memory for storing large-volume geographic information data, and the client may not additionally need to upgrade the geographic information data.
