Digital map manufacturing system to apply the geographical information Using a precise geographical data

摘要

The present invention relates to a system for identifying collected data of geographical information and matching information of GPS coordinates and applying the same to numerical information. More specifically, the present invention relates to a digital map production system which obtains geographical information with minimized error by precisely performing horizontal control of a geographical information collecting device, and re-compares the geographical information with conventional geographical information so as to solve the error between the terrain information and the geographical information.
