Map display system

摘要

A map display system for displaying a linear object on a map in accordance with stored map data is disclosed. The coordinate components of at least two specified points on the linear object and other points thereon crossing straight lines drawn in spaced relationship and in parallel with the straight line connecting the specified points are stored as map data in a memory. The coordinate components thus stored are converted into a display coordinate by a display control to generate a display signal. In accordance with the display signal the linear object is displayed on a display within a predetermined display section.
