Topic:
Is navigation data contained in the trace headers of 2D data exported from SEGY?

Description:
        

Solution:
Yes. If navigation data was loaded for every 20th shot point, it will only be in
the trace header for every 20th shot point when exported to SEGY.

The locations in the trace header for navigation by default are:
X - bytes 73-76       Y - bytes 77-80
