Simple & fast IO for SEG-Y files
https://segyio.readthedocs.io
Segyio is a small LGPL licensed C library for easy interaction with SEG Y formatted seismic data, with language bindings for Python and Matlab. Segyio is an attempt to create an easy-to-use, embeddable, community-oriented library for seismic applications. Features are added as they are needed; suggestions and contributions of all kinds are very welcome.
Segyio does necessarily attempt to be the end-all of SEG-Y interactions; rather, we aim to lower the barrier to interacting with SEG-Y files for embedding, new applications or free-standing programs.
Additionally, the aim is not to support the full standard or all exotic (but correctly) formatted files out there. Some assumptions are made, such as:
The writing functionality in Segyio is largely meant to modify or adapt files. A file created from scratch is not necessarily a to-spec SEG-Y file, as we only necessarily write the header fields segyio needs to make sense of the geometry. It is still highly recommended that SEG-Y files are maintained and written according to specification, but segyio does not mandate this.
