Advanced Line and Trace Description

If you do not have a Line Sequence Number or a Trace Sequence Number in the trace headers of the input files you can use this dialog to supply these values manually. If your data is perfectly rectangular (all lines have the same first and last trace) simply fill in the First Trace, Last Trace, First Line and Last Line values. For irregular 3Ds you will need to use the First Trace of Second Line parameter as well.

Line Geometry

First Trace: Supply the number of the first trace for each inline.

Last Trace: Supply the number of the last trace for each inline.

First Line: Supply the number of the first line in the input files.

Last Line: Supply the number of the last line in the input files.

First Trace of Second Line

First Trace of Second Line: Use this parameter in conjunction with the Trace Counter keyword. Define the Trace Counter as you would any other keyword using the SEG-Y Viewer. It will be an integer value that increments continuously for each trace in the input files. Using the SEG-Y viewer find the value of the trace counter at the first trace of the second line and enter the value in this field.
