ABSTRACT:
An on-vehicle navigation system wherein movement components in an easterly or westerly direction and a southerly or northerly direction for each unit running distance are calculated to determine longitudinal and latitudinal variations. A plurality of locations and the longitudinal and latitudinal coordinates representative thereof are stored in memory so as to be retrieved for display. A contraction scale formed of a rectangular periphery enclosing a longitudinal meridian and a latitudinal parallel passing through the starting location and a longitudinal meridian and a latitudinal parallel passing through the destination location is determined on a display unit so that the current position is effectively illustrated on the display.
