C. Examples
The traverse examples here are the same ones used as previous computation examples so we can check these against earlier results.
1. Bearing Traverse
Figure I5 
Previously computed unadjusted latitudes and departures are:
Line  Bearing  Length (ft)  Lat (ft)  Dep (ft) 
AB  S 68°05'35"W  472.68  176.357  438.548 
BC  N 19°46'00"W  216.13  +203.395  73.093 
CD  N 45°55'20"E  276.52  +192.357  +198.651 
DA  S 54°59'15"E  382.24  219.312  +313.065 
sum: 
1347.57  +0.083  +0.075 
(a) Compute preliminary coordinates from the raw latitudes and departures:
(b) Determine latitude and departure closure errors:
Lat err = N_{A'}  N_{A} = 500.083'  500.000' = +0.083'
Dep err = E_{A'}  E_{A} = 2000.075'  2000.000' = +0.075'
Note that these match the latitude and departure column sums above.
(c) Compute and apply corrections to the coordinates using the Compass Rule, Equation (I3).
Line AB
Because point A is a control point, its coordinates are not modified. The corrections are applied to the line's endpoint, point B.
Line BC
Remember to include the corrections for the previous line.
Line CD
Line DA
The corrected preliminary coordinates match the beginning coordinates of point A.
These coordinates also match those computed in the Coordinates section.
