SOLUTION

Computation of Reference Standard Deviation

A Weighted Example

Computation of Reference Standard Deviation

The weight matrix is multiplied by 12 to achieve the same results given in the text book.

Example 12.1 -- Another Weighted Example

The level net shown in Figure .3 is observed with the following results (The elevation differences and standard deviations are given in meters, and the elevation of A is 437.596 meters.)


What are the most probable values for the elevations of B, C, and D?
