摘要
以经典式和水准式两种全站仪三角高程作业模式代替三等水准测量为例,探讨以全站仪三角高程测量作业评定指标代替电磁波测距三角高程测量作业评定指标。利用全站仪显示高差作为观测量不再把角度和距离分开进行观测和记录,大大提高工作效率。
The substitution of the precision assessing of trigonometric leveling in total station instrument for the precision assessing of EDM trigonometric leveling are discussed, taking the replacement of the three leveling survey with the trigonometric leveling survey of classic type and the level type of total station instrument as the example. The methods no longer carried on the angle and the distances separately and the work efficiency is greatly improved.
