摘　　要：全站仪尤其是智能型全站仪的出现和使用,给测量工作带来了巨大变化,其提供的一些特殊测量功能使过去不易或根本无法完成的任务迎刃而解。如"悬高测量",可方便快捷地测定出空中某点距地面的高度;但其前提条件是欲测高度目标点之天底可以到达并便于安置反射棱镜,否则将无法实施。为此,本文介绍最新推出的一项特殊测量功能——线高测量的方法、步骤,并给出了其基本测量原理和计算公式,同时还重点探讨了其在实际测量中应注意的事项,得出一些有益的结论,供参考。As the appearance of total-station instrument, especially intelligence total-station instrument, great changes have taken place in survey works. Difficult survey jobs could be completed easily by special functions of total-station instrument. For example, it is convenient to measure the height of an aerial target point by REM of total-station instrument on the premise of reaching the nadir point of the aerial target point and settling a reflect prism, or it will not be put into effect. For that reason, a new special survey function of total-station instrument, line-height surveying, was introduced in this paper. The survey principle and practical application were discussed.
