Map display terminal and map display method
First Claim
1. A map display method for displaying a map of a destination position, said method comprising:
- entering a latitude and a longitude of the destination position into a map display terminal;
displaying initially a wide area map of an area including the destination position, the wide area map having a smaller value of a scale ratio than an expanded and more detailed map of the area;
centering the map display on the destination position;
determining a number of display stages;
determining an expansion ratio for each display stage on the basis of a ratio of scale values of the wide area map and the expanded and more detailed map; and
displaying each display stage at the corresponding expansion ratio.

Abstract
A map display apparatus and a map display method facilitate detection of the relationship between a destination position or a current position and the surrounding area, even when a detailed map is to be displayed on a narrow display area. A map display terminal displays a particular position, such as the destination position or the current position, on a map. The current position might be derived on the basis of position information from a Global positioning System. An initial display can be a wide area map having smaller scale than a detailed map and centered destination position or the current position. More detailed maps centered at that position are displayed in stages.

10. A map display method for displaying a map of a destination position, said method comprising:
-
entering a latitude and a longitude of the destination position into a map display terminal;
initially displaying a wide area map of the destination position; and
automatically magnifying the wide area map in a number of display stages to display at each stage a magnified map until a most highly magnified map is displayed, wherein an expansion ratio for each display stage is determined on the basis of a ratio of scale values of the wide area map and the most highly magnified map. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
