Other open-source geophysical packages

The Wikipedia list of free geophysics software provides an up-to-date list of all free geophysical packages in general. Therefore, this section only lists packages that do not forbid usage by commercial entities, and that can interact with Madagascar in a meaningful way, such as:

• providing a graphical interface that can be used to build Madagascar workflows
• importing and exporting RSF datasets directly, without the need to convert to SEG-Y
• being licensed so that Madagascar developers can link to their libraries or include their code directly, in a manner compatible with the GPL

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.
