I recently tried to do something same using C++ (Although it has only been tested on post-stack data).

you could please tell us a little bit about yourself before continuing on to the requested content. There are also numerous free available SEG-Y readers, a very nice list has already been mentioned by Daniel Waechter you can choose any one of them that suits your requirements and the type file format supported. View your spatial data using the free CARIS viewer. Since you are working with the extracted data, I would recommend to use already existing libraries (segpy: one of the best python library I came across). A careful reading of the documentation and getting to know about the type of SEG data you are working on will surely make this task a lot easier. of trace samples is mentioned in the trace headers, etc. Open, view and share your plans from any storage or cloud location on any Mac device running Yosemite, El Capitan, or the new macOS Operating Systems. Group X-coordinate & Group Y-coordinate at. The extraction of trace data is a bit tricky and depends upon various factors like the encoding, whether the no. TraceViewer The SEG-Y format specifies a byte-offset and data format for each trace header field (e.g.

The complete details about the byte locations and encoding formats can be read from the above documentation Also some headers might require conversions from one format to another (e.g Text Headers are mostly encoded in EBCDIC format). The extraction might depend upon the type of data (Post-stack or Pre-stack).

If you need to extract only the headers (Text header, Binary header, Extended Textual File headers and Trace headers) then they can be easily extracted from the SEG-Y file by opening the file as binary and extracting relevant information from the respective locations as mentioned in the data exchange formats (rev2). The answer depends upon the type of data you need to extract from the SEG-Y file.
