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.
标准描述了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
- 跟踪数据
By convention, these files use the.segy或.sgyfilename extensions, but the SEG-Y reader can use any extension.
Reader Overview
The SEG-Y reader module produces an FME feature for each trace in the SEG-Y input dataset. The SEG-Y header is read and is represented by a single FME feature.
Writer Overview
The SEG-Y Writer writes all attributes of a feature to an SEG-Y file. Features of different types are written to different SEG-Y files.
