SEG-Y Text Header Viewer

The Text Header displays the 3200-byte text header in a read-only dialog. The viewer is intended to hold important information about the survey, which may include client, survey company, survey parameters, equipment, processing parameters, and other details. The locations of coordinate fields, the projected coordinate system, and georeferencing of the survey grid may all be found here. If the text header did not get updated as the seismic data was processed, the information in the Text Header might be missing or incorrect.

The standard specifies that the text header is encoded as 3200 bytes of EBCDIC characters (40 lines 80 characters long). Some SEG-Y files store the text header as ASCII instead.
