大比例尺数字测图中“一步测量法”的优化及应用

The Optimization and Applications of “One Step Measurement” in Large Scale Digital Mapping

在分析大比例尺数字测图中采用的"一步测量法"的常规步骤和误差的基础上阐述了"一步测量法"的优点和限定条件,从而提出了"一步测量法"的优化方法,从理论与实际应用两方面论证了优化后"一步测量法"的可行性和便利性,并结合实际测量工作给出了具体的优化流程。

This paper shows the advantages and limitations of the“One Step Measurement”in large scale digital mapping based on the analysis of conventional steps and errors of the“One Step Measurement”. Therefore,This paper proposes the optimization method of the“One Step Measurement”,demonstrates the feasibility and convenience of the op-timized“One Step Method”,gives specific optimization processes combined with the actual measurement. The research of this paper expands the application range of the“One Step Method”,provides important technical guidance to the actu-al measurement.
