To determine if tide has been loaded for a line or lines:
1. Select the track line(s).
2. Select the Selection window.
The Selection window will display line data for the selected line(s) in columns.
The Tide Loaded column shows “Yes” when tide has been loaded for the selected line(s).
The GPS Tide column shows “Yes” when tide has been loaded for the selected line(s).
The Tide Applied column can display one of four values:
• None: No tide has been applied (Merge has never been run, and no ProcessedDepths exist.)
• Observed: The line has been Merged, and choose to apply Observed tides from loaded TID file(s).
• GPS: The line has been Merged, and a GPS tide file has been applied.
• Zoned: The line has been Merged, and a previously loaded ZDF file has been applied.
