List of free geology software
This is a list of free and open-source software for geological data handling 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.
