List of free geophysics software

This is a list of free and open source software for geophysical data processing and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality.

Notice that 'free and open source' requires that the source code is available. Simple being 'free of charge' is not sufficient—see gratis versus libre. The reader interested in freeware (just free of charge) software is referred to the list of freeware geophysics software.

Not true free and open source projects

The following projects have unknown licensing, licenses which place some restriction on use or redistribution, or depend on non-open-source software like MATLAB, and therefore do not meet the Open Source Definition from the Open Source Initiative. (For example, the license may rule out use by certain people or for certain purposes, e.g. in a commercial context.) They are included here because they may be of interest for those in an academic environment or access to tools like MATLAB.
