GPS DIGITAL MAP PRODUCTION SYSTEM FOR OBTAINING ROAD COORDINATE INFORMATION USING GPS MEASUREMENT

摘要

The present invention relates to a numerical map production system, and more particularly, it includes a collection device in which a GPS receiver and a camera are installed, and a numerical map production device that receives coordinate values from the GPS receiver, corrects errors, and converts and records them into numerical map data Characterized in that, input the precise road coordinate values corrected through the standard correction function to the road numerical map of the measurement target area, and obtain road coordinate information using GPS surveying that can input various road surrounding information together with a numerical map It relates to a numerical mapping system that can produce
