Exercise 2: Performing Traverse Analysis

In this exercise, you will reduce some of the survey data using the traverse
analysis Compass Rule adjustment method.
The Compass Rule is a method of corrections. It assumes that the closing errors
are as much due to errors in observed angles as by the errors in measured
distances. The closing errors in latitude and departure are distributed according
to the ratio of the length of the line to the total length of the traverse.
For more information, see the AutoCAD Civil 3D Help topic Traverses.
