CIVE 2004 GIS, SURVEYING & GRAPHICS Faculty of Engineering Civil & Environmental Engineering ASSIGNMENT: CLOSED-TRAVERSE CALCULATION 6 • Due the following week The instructor will indicate in the field the construction site that will be surveyed using a Total Sta-tion and a four- station closed traverse. The instrument will be first placed at point A where several points will be measured and recorded. The surveying crew then proceeded to set stations at B, C and D. Many more site details were also measured from these stations. To check on the accuracy of the survey, a measurement was taken from D back to the initial station (A) and this was labeled A’. When the surveying crew finish the first part of this assignment, the coordinates of A’ will turned out to be slightly different from their initially assumed values at the start of the survey. The differ-ence in coordinates between A and A’ is a measure of the error(s) introduced and these errors can be calculated to estimate the accuracy of the work. This exercise will take you through the steps to perform these

    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.
