COGO Pt. II – Basic traverse calculation [0:25]

We begin this program with a brief discussion of traverse troubleshooting when the disclosure is large, to try to identify the source(s) of the problem. We then progress to identifying the angular error, adjusting the angles, computing the directions (bearings or azimuths), and then determining the error of closure and the relative accuracy or precision. We conclude with the alternative of expressing the relative accuracy in parts per million. Running time 25 minutes.

You will learn…

• Basics of traverse troubleshooting
• Angular error evaluation and adjustment
• Computing directions of the lines
• Determine latitudes (∆ northings) and departures (∆ eastings) of the lines
• Evaluate the error of closure and relative accuracy of the traverse
• Expressing traverse error in parts per million is also covered
