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.
