CON3321 Engineering Surveying 1PE04 Practical Exercise #3 Detail Surveying 3.0 Results Our group was set the measurement point station D, and calculated the whole circle bearing from station D to measured point by using the whole circle bearing from station C to station D. In practical no. 2 traverse exercise, we found the coordinate and whole circle bearing, the result as below: Whole Circle Bearing of Station: Whole circle bearing, Ѳ Whole circle bearing, Ѳ (degree, minutes, seconds)) Whole circle bearing, Ѳ (degree) Horizontal Distance Ѳ from A to B 100°20'30'' 100.341667 11.735 Ѳ from B to C 347°17'25.75'' 347.2904861 20.583 Ѳ from C to D 280°27'32.5'' 280.4590278 9.048 Ѳ from D to A 174°31'52.25'' 174.5311806 19.704 Coordinate of Station: Station A Station B Station C Station D Easting 1200 1211.545 1207.018 1198.121 Northin g 1000 997.893 1017.972 1019.614 Coordinate of Measured Point: ∆E = Distance x sin Ѳ ; ∆N = Distance x cos Ѳ The results were as below: 11

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
