Abstract
A navigation terminal device includes a map information receiving unit for receiving the map of the region around a reference point from the web server by inputting retrieval information; a display screen for displaying the received map; a route line drawing unit for drawing the destination from the starting point of the reference point by screen scrolling, computing the orientation from the reference point to the destination, and displaying the route line which can be traced from the reference point to the destination; a map information requesting unit for requesting again that the web server distributes the map information of the adjacent peripheral region if the destination is not within the received map of the peripheral region; and a route line re-drawing unit for searching the destination by screen scrolling the updated map information, re-compute the orientation and re-draw the route line.
