OpenStereo is an open source, cross-platform software for structural geology analysis.
The software is written in Python, a high-level, cross-platform programming language and the GUI is designed with wxPython, which provide a consistent look regardless the OS. Numeric operations (like matrix and linear algebra) are performed with the Numpy module and all graphic capabilities are provided by the Matplolib library, including on-screen plotting and graphic exporting to common desktop formats (emf, eps, ps, pdf, png, svg).
OpenStereo is released under the GNU General Public License v.3.
An abstract about the software was presented at the AGU 2010 Fall Meeting. A ful paper is being prepared for publication.
