ABSTRACT OF THE DISCLOSURE A novel electronic map display system is disclosed for displaying a map on the basis of a map data stored. Various discontinuous points in each of pre- determined areas included a map to be displayed are stored as structured data in the form of vectors. The discontinu- ous geographic data in each of the areas is stored as image pattern data. A selection signal is produced from a display selection unit for selecting an area to be displayed from the map. In accordance with the selection signal, a display signal is generated from the pattern data and the structured data corresponding to the area to be display- ed. A map of the particular area is displayed on the basis of the display signal of a display control unit.
