Other open-source geophysical packages
The list below was assembled considering the official definition of the "open-source" term from the Open Source Initiative.
Comprehensive seismic processing suites
These suites include a wide range of algorithms and tools, covering most of the needs of a seismic data processing and imaging researcher at the time when they were developed.
- Seismic Unix (BSD-style license), maintained by John Stockwell (Center for Wave Phenomena, Colorado School of Mines)
- Free USP, a processing package originally developed by Amoco and released by BP
- DDS (Data Dictionary System), also released by BP.
- CPSeis, the former processing system of ConocoPhillips (also downloadable from OpenGeophysical).
There are also other publicly available packages, with a smaller number of utilities than the ones described above, but each having unique capabilities, in its own way. Browsing SourceForge's Earth Sciences section may reveal others as well.
