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 and users are given a free software license. Simple being 'free of charge' is not sufficient—see gratis versus libre.

Geographic information systems (GIS)

This important class of tools is already listed in the article List of GIS software.

Not true free and open-source projects

The following projects have unknown licensing, licenses or other conditions which place some restriction on use or redistribution, or which depend on non-open-source software like MATLAB or XVT (and therefore do not meet the Open Source Definition from the Open Source Initiative).

Name Description Originator License Platforms Language Notes
Noddy[23] 3D geological and geophysical modeling Tectask, IUGS Custom permissive license Microsoft Windows C++ Uses proprietary XVT libraries; requires (free) registration
BasinVis,[24][25] Basin visualization of sedimentary fill and subsidence Eun Young Lee, Johannes Novotny LICENSE Cross-platform Matlab
Geomodelr[26] Geological modelling from cross sections Geomodelr, Inc. SaaS - AGPL Cross-platform Python Allows creation of public geological models in its web platform for free and query the model with an Open Source Python Package
BGS Groundhog Desktop[27] Geological modelling from cross sections British Geological Survey OGL - Open Government Licence MS Windows Java Free to use software to digitize geological cross-sections, and display and edit borehole logs
