Ex29-4 : Compute the error of closure for the traverse defined in Example 29.1
Figure Example 29.4
Solution : Refering table 29.2 and using equations 29.7 and 29.8 respectively, we get
Error in departure, dD= S departures = - 0.983
Error in latitude, dL= S latitudes = - 0.606
and the direction of the error is given by
q = 58° 20' 49".16
Since the both the errors in departure and latitude are with negative sign thus, it indicates the error is in third quadrant and 180° is to be added to find the azimuth of the error of closure. Thus, the azimuth of the error of closure is (180° + 58° 20' 49".16) = 238° 20' 49".16
