Zusammenfassung
Since the original SEG Y Data Exchange Format (revision 0, reference
page 45) was published in 1975 it has achieved widespread usage within
the geophysical industry. This widespread usage has brought about
many proprietary variations. Since the publication of SEG Y rev 0,
the nature of seismic data acquisition, processing and seismic hardware
has changed significantly. The introduction of 3-D acquisition techniques
and high speed, high capacity recording media dictate the need for
revisions to the SEG Y rev 0 format. The major changes introduced
by SEG Y rev 1 are: standardizing the location of header information
needed for current processing practices and defining a SEG Y data
set as a byte stream format. The SEG Technical Standards Committee
strongly encourages producers and users of SEG Y data sets to move
to the revised standard in an expeditious fashion.
