Other open-source geophysical packages
The Wikipedia list of free geophysics software does a fine job of keeping track of all packages in general. Therefore, this section will only list packages that can interact with Madagascar, either at source code / linking level (GPL, or compatible to be linked by GPL-ed programs), or through file format converters, and that have no commercial usage restrictions.
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)
- SEPlib (BSD-style license), maintained by Bob Clapp at the Stanford Exploration Project (SEP)
- 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
Specialized tools
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.
