The SEG-Y Reader/Writer provides FME with direct access to data in SEG-Y format.
Overview
The SEG-Y format is a tape standard developed by the Society of Exploration Geophysicists. The first standard was developed in 1973 and many modern variations exist.
The standard describes the layout of the binary data as follows:
- a 3200-byte EBCDIC reel header
- a 400-byte binary reel header
- trace records consisting of:
- a 240-byte binary trace header
- trace data
By convention, these files use the .segy or .sgy filename extensions, but the SEG-Y reader can use any extension.
