Shifting Station Numbers

Use Shift to shift a range of station numbers by a specified number of feet. You can add or subtract a fixed footage to station numbers for a range of readings in a survey. This function is typically used if station numbers are not known when performing the survey and they need to be shifted to correct station numbers.

To shift station numbers, follow these steps:

1	Click the Select ROWs button to open the Select ROWs window (Figure 7-56). Select the pipeline segment(s) with the facilities you want to work with, then click Save to close the window.

2	If the ISM module is not open, click Modules > Indirect Survey Manager (ISM).

3	Click Data Entry > Edit ISM Data to open the ISM data entry grid. Then click a button labeled with the type of continuous survey data you want to work with, such as the CIS button (Figure 7-63).

4	Select a survey folder with survey readings you want to shift. Click the down arrow in Selected Continuous Survey and select a survey folder in the selection list.

Note: If you want to collapse the Selected ROWs panel, click the Selected ROWs bar. Clicking the bar again expands the panel.

5	Click Survey Maintenance to open the Survey Maintenance dialog box. Then click Shift (Figure 7-64).

6	Type a starting station number in the field Starting Station Number and an ending station number in the field Ending Station Number.

7	Type or select the number of feet in the Distance field. Clicking the up arrow increases the value; clicking the down arrow decreases it.

Note: Clicking the Windows close button cancels the operation and closes the dialog box.

8	Click Apply to shift station numbers and update the data entry grid.
