Run a traverse analysis 1 On the Survey tab, in the list view, right-click Traverse 1. Click Traverse Analysis. 2 In the Traverse Analysis dialog box, specify the following parameters: ■ Horizontal Adjustment Method: Compass Rule ■ Vertical Adjustment Method: Length Weighted Distribution Use the default values for the other properties. 3 Click OK. The analysis runs, and the following files are displayed in the ASCII text editor: ■ Traverse 1 Raw Closure.trv: Displays the horizontal closure and angular error. ■ Traverse 1 Vertical Adjustment.trv: Displays a report of raw and adjusted elevations from the vertical adjustment methods. ■ Traverse 1 Balanced Angles.trv: Displays the adjusted station coordinates derived from balancing the angular error and horizontal closure with no angular error. ■ Traverse 1.lso: Displays the adjusted station coordinates based on the Horizontal Adjustment Type setting (Compass Rule). 4 Close all the text files. A dialog box notifies you that you should use the Process Linework command to update the figures with the new traverse information. Reprocessing the survey linework is a manual process. You will see how to update the linework in the following steps. 5 In the Survey Network Updated dialog box, click Close. 6 In Toolspace, on the Survey tab, under Import Events, right-click Survey-1.fbk. Click Process Linework. The Process Linework dialog box enables you to reprocess the survey network linework connectivity after you make corrections to the survey data. When the survey database is updated following a traverse analysis, the following adjustments to the data that references the traverse take place: ■ Observed station points are updated and added to the Control Points collection.
