A digital map production system that improves accuracy by checking real-time reference points

摘要

The present invention relates to a digital map production system for improving the accuracy by checking real-time reference points, and more specifically, to a digital map production system for improving accuracy by checking real-time reference points, which can easily confirm a change in geographical information due to a natural or artificial terrain change and increase the accuracy of the digital map by updating the digital map based on erroneous data, and which can maintain a stable posture without shaking even if an installation place of a geographical information collecting apparatus installed on the ground surface determined as a check target point is not solid so as to generate accurate information from a support information collecting apparatus.
