Other open-source geophysical packages
The Wikipedia list of free geophysics software does a fine job of keeping track of all packages in general, and having more contributors tends to be much more up to date. Therefore, this sections 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/non-commercial usage restrictions.
To avoid redundancy with the Wikipedia list, the list below will be sorted by the manner of interaction with Madagascar.
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
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.
