SEG-Y Writer Parameters

Coordinate Format

Specifies the binary encoding that the reader will use to interpret the coordinate values in the binary trace header.

  • 4-byte Integer: Specifies that the stored value is encoded as a signed integer.
  • 4-byte IEEE Floating-point Value: Specifies that the stored value is encoded as an IEEE floating point number.
  • 4-byte IBM Floating-point Value: Specifies that the stored value is encoded as an IBM floating point number.

Coordinate Location

Specifies the byte offset of the coordinate values in the binary trace file. The coordinate values are stored as two 4-byte values.

  • Standard/SeisX SEG-Y Format: This is the default. The X coordinate is written to locations 81 to 84, and the Y coordinate is written to locations 85-88.
  • Custom: You can also specify a custom value for the coordinate location. For example, if the byte offset of 81 is specified, the X coordinate will be written to locations 81 to 84, and the Y coordinate will be written to locations 85 to 88.
