摘　　要：简述了传统悬高测量原理,针对高压线投影到地面不准确的问题,从另外一个角度出发,提出采用道路测量软件精确确定高压线垂直投影点,从而提高悬高测量精度。This paper introduces the fundamental rationale of remote elevation measurement with total station.For high-voltage lines projected onto the ground inaccurate,from another point of view,a method using of roads software is proposed to accurately determine the vertical projection points to improve the accuracy of remote elevation measurement.
