全站仪大比例尺数字化测图精度分析和探讨

Analysis and Discussion on Accuracy of Large Scale Digital Mapping in Total Station

本文依据误差传播理论,对影响全站仪平面精度和高程精度的误差进行推导和计算,并对三种常用精度指标的全站仪(2"级、6"级和10"级)测量平面精度和高程精度进行计算和分析,其结论可为全站仪大比例尺数字化测图提供参考。

Based on the error propagation theory,this paper deduces and calculates the errors that affect the plane and elevation accuracy of the total station and uses the three total stations(2",6"and 10").The measurement plane accuracy and elevation accuracy are calculated and analyzed.The conclusions can provide reference for the large-scale digital mapping of the total station.
