GIS DIGITAL MAP PRODUCTION SYSTEM OF ROAD INFRASTRUCTURE BY CONFIRMING GIS AND REFERENCE POINT LOCATION INFORMATION

摘要

The present invention relates to a numerical map production system, and more particularly, to a correction computer installed in a vehicle traveling on a street to receive photographing information, camera position information, and camera posture information, and an existing numerical map using data from the correction computer characterized in that it includes a GIS server that can update It relates to a digital map production system for road infrastructure through GIS and reference point location information that can improve the data collection accuracy of a camera using a buffer mechanism and an air buffer unit.
