DRAWING OF THE IMAGE SYNTHESIS SYSTEM REFERENCE POINT FOR IMPROVING THE PRECISION OF DIGITAL MAPS

摘要

The present invention relates to a synthesis system for an imaging datum point for improving accuracy in a numerical map. More specifically, the present invention relates to a synthesis system for an imaging datum point for improving accuracy in a numerical map which allows a user to be immediately aware of danger ahead even if the user does not check the navigation device in advance, by using a transmitter which becomes a datum point in the formation of the numerical map. Thus, the user can cope with danger ahead. To this end, the apparatus of the present invention comprises: a global positioning system (GPS) satellite (S); a transmitter (100) transmitting information on a road condition; and a navigation device (200) receiving the information on the road condition from the transmitter (100) so as to display the same.
