Reduce to single line
Reduce to single line command reduces tie lines to single line observations. As a result, each tie line is placed in only one strip. This is useful for solving calibration issues of a multi-scanner system because trajectory drift issues do not effect the solution for the whole data set anymore.
To reduce tie lines to single lines:
1. Collect tie lines with setting Separate scanners on. See Define Tie Lines for more information.
2. Select Reduce to single line command from the File pulldown menu.
A dialog is shown which asks for confirmation of the step.
3. Click OK in order to reduce the tie lines.
4. Save the tie lines into a new tie line file.
