在测量工作中,如河道、渠道、堰坝等纵横断面图的测量,经常要采用视距测量的方法,求出测定两点间的水平距离和高差(高程)。经纬仪视距测量,由于速度快,操作简便,已在工程测量中得到了广泛的应用。在实际工作中,要用电子计算器或者视距计算表求出水平距离和高差,既耗时费工,又容易出错。虽然利用可编程序计算器能够提高测量工作效率,但仍然不便于利用电脑把测量成果进行内业计算复核。利用计算机电子表格的制表、
In surveying work, such as the vertical and horizontal sections of rivers, channels and barrage, the horizontal distance and height difference (height) should be determined by means of line-of-sight measurement. Theodolite line of sight measurement, due to speed, easy to operate, has been widely used in engineering surveying. In the actual work, it is necessary to calculate the horizontal distance and the height difference with the electronic calculator or the line-of-sight calculation table, which takes time and labor and is prone to error. Although the use of programmable calculators can improve the measurement efficiency, but still not easy to use the computer to measure the results of the field calculation review.
