# Traverse Column

A Traverse Column is automatically added to the spreadsheet, if at least one Traverse has been defined in the Traverse Information dialog.

The Traverse Column is used to assign the data units to the traverse from which they were measured, by entering the appropriate Traverse ID number. This allows the user to identify data from different traverses, and also to apply the correct Terzaghi Weighting to the data.

Traverse Column Values

The numbers in the Traverse Column should normally correspond to the Traverse ID numbers in the Traverse Information dialog.

However, Dips will allow Traverse Column entries which are blank, or do NOT correspond to defined Traverse ID numbers in the Traverse Information dialog. In this case, when the Terzaghi Weighting is applied to contour or rosette plots, these data units will be assigned a weighting of ONE (1.000), since no traverse orientation information is available.

Traverse Column Position

The Traverse Column will always be either the THIRD or the FOURTH column in the spreadsheet, depending on whether or not a Quantity Column exists.

- If the Quantity Column does NOT exist, then the Traverse Column will be the THIRD column, immediately following the Orientation Columns.

- If the Quantity Column exists, then the Traverse Column will be the FOURTH column, immediately after the Quantity Column.

Adding / Removing the Traverse Column

- The Traverse Column is automatically added if at least one Traverse is defined in the Traverse Information dialog.

- It is automatically removed if ALL traverses are deleted in the Traverse Information dialog.

- The Traverse Column CANNOT be added / removed with the Add Column / Remove Column options.
