ABSTRACT:
A display system in a navigation apparatus according to the invention has course searching means (13) for searching out an optimum course based on position information, node data (21), intersection data (19) and road data (23), and scale ratio setting means (15), wherein the scale ratio of a displayed map is set in conformity with distance between a present position and a destination, and roads are selectively displayed on a display unit (31) in conformity with the scale ratio.
Further, the invention has a data processing controller (46) for performing processing based on a departure intersection entered at an input unit (43), a display unit for displaying, based on the results of processing, an intersection diagram comprising the departure intersection, a peripheral road network and landmarks, and touch keys (35) such as a verification key for displaying direction of travel on the displayed intersection map, and a rotation instruction key for rotating and displaying the intersection diagram.
In addition, the invention includes display means (48) for displaying an intersection diagram, in which direction of travel is pointed upward, and intersection landmark patterns, map data (53) stored as a relationship among roads, intersections and intersection landmarks, and as coordinated, and a data processing controller (46) for reading, from the map data (53), positional coordinates of an intersection landmark to be displayed, rotating and enlarging the positional coordinates and transforming them into coordinates of a display area set on the display means, and sending an output signal to the display means (48) in such a manner that the intersection landmark patterns are displayed on the transformed coordinates.
