The field SEG-Y data files may be processed and plotted using seismic processing data software. Some programs shows seismic data in SEG-Y, CWP/SU, CGG CST formats on screen of your personal computer. [1]
Some features that you can see in a SEG-Y are:
- Standard integer (2,4 bytes) and IBM float (4 bytes) sample formats support
- Nonstandard integer(1 byte), float IEEE (4 bytes) sample formats
- Various seismic display modes (Wiggle trace, variable area, variable density, color)
- Import-export color palettes to text file
- Scaling seismic image, gain control, axes labeling setup
- Plot seismic to printer (plotter)
- Image export in Bitmap (.bmp) and PostScript formats.
- SEG-Y trace headers display (formats Integer*1,*2,*4, IEEE Float*4,*8, IBM Float*4 are supported)
- Search trace by header item value
- Data samples browsing
- Text header and binary editor
- Band pass filter, automatic gain control (AGC)
- Headers consistency check
- Write whole SEG-Y file or part of it to disk in SEG-Y (IBM-32/IEEE) or CWP/SU format with ability to select data on base of trace index or trace header value or trace header expression and given time interval
- Parameters can be applied to recorded data (filter, AGC etc).
- Export trace(s) sample and header values to text file
- Import trace headers values from text file
- Trace shift according with “Delay Recording Time” trace header value
- Selection of traces to be displayed by trace index or header value and by expression
- Trace headers change by means expressions
- Trace sorting
- Open and fix files containing wrong data in binary header (Recovery Mode)
- Single trace header item editing
- Disc directory browsing
- Power spectrum calculation and display
