A four-sided traverse is measured in the field, as illustrated below. Point A is a survey mark with known coordinates of 100.000E, and 150.000N.

 

From	To	Bearing	Distance
A	B	97o 52' 17"	158.460m
B	C	?	180.973m
C	D	?	181.270m
D	A	?	233.090m

a)  Determine the angular misclosure of the traverse ABCD. Provide your answer in a sexagesimal system rounded to the nearest 1”.

b)  Determine the adjusted bearings of lines BC, CD, and DA. Provide your answer in a sexagesimal system rounded to the nearest 1”.

c)  Using the adjusted bearings and distances for the traverse ABCD, calculate the following:

(i) the linear misclosure (in meters correct to 3 decimal places)

(ii) the precision in reciprocal form

d)  remove the linear misclosure using Bowditch’s rule and calculate the adjusted coordinates in meters correct to 3 decimal places.
