Which SEG-Y formats are supported by the SEG-Y Loader?
SEG-Y is the only supported format for transferring 2D and 3D trace data into Insight.
The DUG SEG-Y Loader supports both SEG-Y Revision 0 (1975) and Revision 1 (2002).
The trace data format must be specified in the Data Sample Format Code. The codes are:
1 = 4-byte IBM floating-point
2 = 4-byte, twos complement integer
3 = 2-byte, twos complement integer
4 = 4-byte fixed-point with gain (NOT SUPPORTED)
5 = 4-byte IEEE floating-point
6 = Not currently used
7 = Not currently used
8 = 1-byte, twos complement integer
Insight does not support SEG-Y in 4-byte fixed-point with gain format.
