导线近似平差计算

随着红外线测距仪的普及以及全站仪的广泛应用，量距精度也逐步提高，导线测量逐步取代了传统的三角测量，成为一种日益流行并深受广大测量工作者青睐的平面控制测量方法。本文基于此设计了在Visual Basic （VB）平台上对附和导线，闭合导线和支导线进行编程解算的软件。

Approximate Adjustment Calculation of the Traverse

Along with the popularity of infrared ray range finder and the extensive use of total station ,the accuracy of distance measurement is improved gradually too .So the trav-erse survey has been substituted for the traditional triangulation ,and is an horizontal control measuring technique which is more and more popular and is well favored by surveyors .The software is designed based on Visual Basic （VB） platform to calculate echo conductor ,closed traverse ,and open traverse .
