"To be conscious that you are ignorant is a great step to knowledge." Benjamin Disraeli, British politician (1804 - 1881)

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.

You must hand in the cover sheet for the assignment and printouts of your spreadsheet for Parts 1, 2, and 3 and your work for Parts 3 and 4. Also, submit your Excel file for Parts 1, 2, and 3 to Canvas.

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 if it provides 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 individual cells. Compute the latitudes and departures, closure error, traverse precision, latitude and departure corrections, and balanced latitudes and departures. The values listed in the yellow cells are input data, and those shown in the green and blue cells are computed.

Part 1: Compute the corrected latitudes and departures for the data displayed in the above example.

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 the homework format)

Part 4: Use the information in the course syllabus to compute your current grade in the class.

Part 5: Read the Chapters 17 and 18 in the "A Mind for Numbers" by Barbara Oakley.
