Differential leveling observations are used to determine differences in elevation between
stations. As with all observations, these measurements are subject to random errors that
can be adjusted using least square adjustment. This program performs the leveling
adjustment by using least square adjustment.
Input Format
The file format includes .dat, .txt and any files that have structure below:
B-Benchmark value for leveling
Example: B 1 437.596
S-Station elevation value that will used to adjust
Example: S 2 1 10.509 0.006
Example Case
The level net shown in figure below is observed with the following results (the elevation
differences and standard deviations are given in meters and elevation of A is 437.596m):
