Question

Compute the azimuths for each course of the closed traverse
assuming a fixed azimuth of 182^{o}30’ for line AB. Angle
to the right at A = 118^{o}27’; B =107^{o}03’; C =
105^{o}35’; D = 130^{o}14’; E = 79^{o}07’.
What is the angular misclosure?

Answer #1

compute bearings starting from given bearing at A, then close the travesre at A.

Check whether the angle at A matches with the given one or not.if not, the difference is the error we get or misclosure.

Consider a polygon traverse. The azimuth of side AB is fixed at
35∘09′32′′.A=57∘00′50′′, B=88∘24′45′′, C=126∘36′58′′,
D=46∘03′25′′,E=221∘53′52′′. (Note: Line BC bears NW.) The lengths
of the sides (in meters) are as follows: AB=383.808, BC=360.209,
CD=342.204,DE=336.210, and EA=267.527. The coordinates of station A
are X=310,630.892m and Y=121,311.411m.

Observations, using an electronic theodolite were taken in the
field for 5 sided polygon traverse, ABCDE. These observations are
tabulated below. The coordinates of station A are 1000.000m E,
1000.000 m N. Orienting bearing of leg AB is 73°00’00”. Leg BC is
in S.E quadrant.
Using these data determine the adjusted coordinates of B, C, D and
E applying Bowditch’s rule.
