Hint for Question 2: Determine absolute values of latitudes and departures. Calculate bearing angles as

tan -1

(Departure/Latitude). By visually inspecting the direction of the line segment determine the

azimuth

Hint For Question 3: Calculate the forward and backward azimuths of all the directions. Then Calculate

the co-ordinates of all the points (To do this you need to first determine the latitude and departure of

each side of the traverse plot). Adding all the latitude and departure values you will find out the linear

error and thus the Precision Ratio.

REFERENCE MATERIAL: Example solved in the class from GPS lecture. The solution is also available on

Titanium.

Question 3: Mapping of a ground in front of CSUF Engineering building was done with a four sided

closed traverse. Assuming that the angle measurement is accurate, interior angles of only three

traverse stations were measured. Northing, Easting, and Elevation of stations C and D were measured

with GPS device. Rest of the surveying was done with the total station. The results obtained with field

surveying are shown in the following tables. With the provided information, please calculate the

Northing, Easting, and Elevation of stations A and B. Please calculate the precision of distance

measurement with the total station.
