Abstract
Accuracy of position by Mobile Mapping System depends on the positioning accuracy by Global Navigation Satellite System. When positioning by GNSS is impossible, it is necessary to adjust by Ground Control Point. However, benefit of low cost and efficient measurement is impaired by installation of many Ground Control Point. Prior research has been already studied installation method of GCP, but it didn't consider the driving speed. The experiment was executed to examine the relation between driving speed and intervals of GCP. It was inspected the relation between the cumulative error and elapsed time. As a result, driving speed is faster the better accuracy of position. The Increase tendency of error value against time is constant regardless of driving speed. When target accuracy is set the 0.10m in horizontal direction and driving speed 60km/h, the positioning accuracy satisfied the target range up to 166m after adjustment.
