Errors & AdjustmentsTheory & Practice in SurveyingWeighted Measurement

Weighted Measurement – Problem 1

From the level net shown, it is required to compute the adjusted elevations of $BM_2$, $BM_3$, and $BM_4$ if $BM_1$ = 100m.
a = +21.14m.
b = +5.08m.
c = -10.06m.
d = -15.96m.
e = -5.20m.

The correction must be such that the elevation difference between any pair of benchmarks shall be the same by whatever route is computed.
