Abstract
A moving body track indicating system for displaying the track of a moving body along with latitude and longitude line markers and cursors on an indicating device such as a cathode-ray tube. The displayed pattern can be automatically magnified or reduced and shifted to a desired position. Cursor markers are displayed parallel to the latitude and longitude line markers with identifying symbols displayed along with the cursor markers. A reference point is automatically readjusted wherein the moving body, a ship in the preferred embodiment, moves beyond the edge of the display surface.
