Digital map updating system through the reference point by jipieseu (GPS) coordinates the synthesis of the visual image

The present invention relates to a digital map update system by synthesizing GPS coordinates by reference points of a video image. More particularly, the present invention relates to a system and method for updating a map image output to navigation according to a natural or artificial change in a specific area, It is possible to output a map image similar to the shape of the tide and to reflect the change of the shoreline in real time on the map image by confirming the difference of the tide only. Thus, when the user travels on the road adjacent to the coastline, the position of the coastline by the tide of the tide included in the map image is reflected in the navigation, so that the user can easily understand and judge the moving terrain A numerical map gang through synthesis of GPS coordinates by reference point of image It relates to the system.
