Dec 6, 2023 · The field SEG-Y data files may be processed and plotted using seismic processing data software. The SEG-Y (sometimes SEG Y or SEGY) file format is one of several data standards developed by the Society of Exploration Geophysicists (SEG) for the exchange of geophysical data. Opens a segy file and tries to figure out its sorting, inline numbers, crossline numbers, and offsets, and enables reading and writing to this file in a simple manner. SGY files may store sweep frequency, types, and length, impulse signal polarity, projection zone and method, and other metadata. It contains geophysical data in binary and textual format, which includes the coordinates of reflected seismic waves.
