Abstract
A latitude and a longitude of each of arbitrary two points on a map shown on a display are specified based on map information, and a quadrilateral having a line between the two points as one of the diagonals thereof is formed.
Claims10
A method of processing map information, comprising the steps of:
- designating two arbitrary points on a map and specifying a latitude and a longitude of each;
- displaying a map area including said two arbitrary points on a display;
- designating an arbitrary third point within the map area on the display;
- and
- calculating a latitude and a longitude of said third point based on a ratio between the number of dots representing vertical and horizontal distances between said two arbitrary points, and the number of dots representing vertical and horizontal distances between said third point and one of said two arbitrary points.

A method of processing map information, comprising the steps of:
- designating two arbitrary points on a map and specifying a latitude and a longitude of each;
- displaying part of a map area including said two arbitrary points on a display;
- designating an arbitrary third point within the part of the map area on the display;
- and
- calculating a latitude and a longitude of said third point based on a ratio between the number of dots representing vertical and horizontal distances between said two arbitrary points, and the number of dots representing vertical and horizontal distances between said third point and one of said two arbitrary points to identify them, a resolution of said map area being the same as a resolution of the display.
