List of free geology software

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

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.

Well logging & Borehole visualisation[edit]

SGS-Geobase [1] Drilling data logger that can interface with SGS Genesis SGS Canada Inc. GPL Windows & Microsoft Access Microsoft Access VBA Microsoft Access is not necessary, the free runtime is sufficient.

Geographic information systems (GIS)[edit]

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

Not true free and open-source projects[edit]

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).
