Objective
The purpose of this assignment is threefold: (1) develop a spreadsheet that
computes the balanced latitudes and departures of a traverse given the bearings
and distances of each side, (2) compute the bearings of a traverse based on
survey data and a reference bearing, and (3) compute your current grade in the
class.
Write a spreadsheet that computes
corrected
latitudes and departures for a traverse where angles are given by their
bearings. The figure below shows a typical spreadsheet
layout for this problem. Your spreadsheet may look different as long as it provides
for the same input and parameter definitions. Note that the directions N/S and E/W
are in separate cells. Also, the values for degrees and minutes are in separate
cells. Compute the latitudes and departures, closure error, precision of the
traverse, latitude and departure corrections, and balanced latitudes and
departures. The values listed in the yellow cells are input data, and the values
shown in the green and blue cells are computed.

Part 1: Compute the corrected latitudes and departures for the data displayed in the
example shown above.
Part 2: Use your traverse spreadsheet to compute the corrected and balanced latitudes and
departures for the traverse shown below.

Part 3: A four-sided closed field traverse has the following distances in feet: AB =
636.45; BC = 654.49; CD = 382.85; and DA = 512.77. The interior angles are as follows (measured as angles to the right): A
= 81º 23'; B = 72º
33'; C = 89º 40'; and D = 116º
24'. The bearing of AB is S
33º 19' W and the side BC is in the SE
quadrant. Determine the bearings of each side and then use your traverse spreadsheet to compute the corrected and balanced latitudes and
departures for the traverse. Show all work for determining the
bearing of each side (follow homework format)
Part 4: Use the information in the
course syllabus to compute your current grade in the
class.

Lastly, a web page describing the CIVL 1112
homework
policy is available. Read it before you turn in this assignment. You will be graded
throughout the semester according to the policy outlined in it.
