A Traverse file is a binary file which is used to store and adjust traverse observations and co-ordinates. It may contain up to 255 interrelated or nested traverses.
A Traverse file may be processed to determine adjusted co-ordinates of the previously unknown traverse points. It also may be edited to correct data recording or data entry errors.
Traverse files always have a TRV extension.
Note: If you wish to adjust a network instead of a traverse, refer to the Control File.
Creating Traverse Files
You may create a traverse file and add data to it using the Traverse File Editor. This editor is run by selecting the Field Transfer/Resolve/Traverses command.
Traverse observations may be entered manually in the control file editor. Alternatively traverse observations may be automatically extracted from a Field File into the traverse file using the File/Extract command in the traverse file editor.
Editing Traverse Files.
Once the data is in a control file, it may be viewed or edited to correct data recording and data entry errors using the Traverse File Editor.
Adjusting Traverse Files.
This is the process of performing an adjustment on the contents of a traverse file. Use the Traverse File Editor Solve menu to select the adjustment required.
Transferring Adjusted Co-ordinates to the Data Base.
After an adjustment is successfully carried out, you can save the adjusted values to the traverse file and then use the Solve/Update commands to transfer the adjusted co-ordinates or elevations to the currently open data base.
When a Field File is reduced using the Resolve/Reduce Field File command, co-ordinates of points which exist in the data base will be used in preference to co-ordinates of the same point identifier located in the Field file.
Therefore, extracting the traverse observations from a field file, adjusting the resulting traverse file, and transferring the results to the data base prior to reducing that field file will ensure that the reduced data from the field file is correctly adjusted.
