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.

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.
