【论文摘要】从实际实施跨河水准测量的两种方法所得结果精度的比较,并利用三角高程测量单向观测的高差计算公式及对跨河水准测量的高差中数中误差进行的估算,验证了利用高精度全站仪实现高精度跨河水准测量的可靠性。
【Abstract】 It is reliability that using high precision electronic total station could accomplish high precision river-crossing leveling.For this conclusion,we have compared two methods of practical river-crossing leveling,used trigonometric leveling to unidirectional observe elevation difference calculation formula and estimated the measurement error in mid-values of altitude differences of river-crossing leveling survey.
