Using GPS three-dimensional information to determine the method and precision of control point coordinates of the photograph, and through the implementation of industry sector three-encryption detection and the analytic space work inside and outside, we prove that the method not only meets the 1:10,000 scale precision aerial mapping, but also improves the efficiency of 3 - 10 times more than traditional union measuring method. For survey areas under difficult visibility conditions and with less known large places, using multiple GPS control points is the best method.
