摘要
根据水准网数据特征,按已知数据、观测数据以及水准网边和点的相对位置关系设计了数据组织结构。基于间接平差模型,在VB环境下设计开发了水准网平差系统。选取了一组水准网数据,计算了水准网的高程平差值、高程中误差、高差平差值和高差中误差,并与已有计算结果作了对比,验证了程序编制的正确性和系统运行的可靠性。
On the basis of the data structure designed,according to the known data,observation data and the relation of points and lines by the characteristics of the leveling net.Using VB to code,designes and developes an adjustment system of levelling net,based on indirect adjustment model.Choosing a set of levelling net data to calculate adjusted value and mean square error of elevation and elevation difference,and makes a comparison with existing results,and verification the validity of the programming and the reliability of the system.
