How to read/restore big data file (SEGY format) with C/C++?

I am working on a project which needs to deal with large seismic data of SEGY format (from several GB to TB). This data represents the 3D underground structure.

Data structure is like:

1st tract, 2,3,5,3,5,....,6
2nd tract, 5,6,5,3,2,....,3
3rd tract, 7,4,5,3,1,....,8
...

What I want to ask is, in order to read and deal with the data fast, do I have to convert the data into another form? Or it's better to read from the original SEGY file? And is there any existing C package to do that?

Solution

  • When dealing of data of that size, you may not want to convert it into another form unless you have to - though some software does do just that. I found a list of free geophysics software on Wikipedia that look promising; many are open source and read/write SEGY files.

    Since you are a newbie to programming, you may want to consider if the Python library segpy suits your needs rather than a C/C++ option.
