Program Design of Leveling Network Adjustment

Abstract This design chooses Visual Basic 6.0 software as the development platform, and use the model of adjustment by observation equation. According to the principle of least squares, it can achieve the automatic flat difference calculation of leveling network data . According to features of location between the level points, the data which is known or unknown and the correspondence between observed data. We can edit data organization structure, and store it in a text file. We can realize the function of reading leveling network observation data from the text file, calculating the unknown point approximate elevation and constructing error equation automatically by editing code in Visual Basic 6.0 software. At the same time, we can carry out the matrix operation and solve the error equation through editing the code, as well as to obtain the most probable value of elevation of the unknown point in the leveling network and measure precision. Finally, the adjustment result will be outputted and stored in text file.

The interface of adjustment program is friendly and easy to operate, what is more, we have used examples to verify the accuracy of adjustment calculation and the stability of the software, the program is easy to grasp and use, which has a certain practicality.

This paper has 15 figures, 9 tables, 10 references.
