SEG-Y / SEGY
============

.. shortname:: SEGY

.. built_in_by_default::

This driver reads files in SEG-Y format. Those files are binary files
that contain single-line seismic digital data. The driver will report
the attributes of the trace header (in their raw form, see the SEG-Y
specification for more information), and use the receiver group
coordinates as geometry. The sample values are also reported.

A layer "{basefilename}_header" is also created and contains a single
feature with the content of the text and binary file headers.
