What is a SEGY File Type?

The SEGY files are used to map and measure the properties of the earth sub-ground. They store data recorded by various seismological instruments that are used to send a controlled energy to the subsurface and record reflected waves, much like sonar devices. The SEGY files can be opened and viewed at different programs, such as Geopsy, Seismic SEGY Toolkit and kogeo.

The SEGY format evolved from the 1975 SEG format, which was widely used in the geophysical industry. The format has evolved over the years as a result of its extensive use, with more possibilities added in subsequent revisions and variations.

SEGY files can also be saved as .SGY files.
