1 OpenStereo: open source, cross-platform software for structural geology analysis Carlos Henrique Grohmann & Ginaldo A.C. Campanha Institute of Geosciences, University of São Paulo, Brazil AGU 2010 Fall Meeting, San Francisco Grohmann & Campanha (IGc-USP) OpenStereo AGU 10 1 / 35

2 Why yet another stereonet software? There are several options available for structural geology analysis Free download Stereonet, StereoNett (Stereo32), GeoOrient, T-Tecto, Orient... Comercial licenses Dips, RockWorks Basic tools Plotting poles, great circles, rose diagrams, rotating data More specific tasks Paleostress, Rock slope stability Grohmann & Campanha (IGc-USP) OpenStereo AGU 10 2 / 35

3 Why yet another stereonet software? Lots of options, lots of differences Data format for input Text files, spreadsheets Graphical User Interface From very simple to professional Graphics exporting Metafiles (windows only), bitmaps, print screen Operating Systems Most are for Windows, some are for Mac, but none is for *nix Grohmann & Campanha (IGc-USP) OpenStereo AGU 10 3 / 35

4 Oh, that s why Our goal was to create a software that could address these problems Cross platform (run in the same way on Windows, Mac, *nix) Clean interface Simple data input (text files) Good set of tools Free (as defined by the Free Software Foundation) Grohmann & Campanha (IGc-USP) OpenStereo AGU 10 4 / 35

5 Tell me more OpenStereo is Free and Open Source Software (FOSS) Licensed under the General Public License (GPL) v.3.0 or above Written in Python Widely used programming language, easy to learn Uses numpy and matplotlib Good tools for numeric analysis and graphics plotting/exporting GUI is written in wxpython Consistent look-and-feel regardless the OS To run it you need Python 2.6, numpy, matplotlib 1.0, wxpython 2.8 We recommend the Enthought Python Distribution or PythonXY (Windows or Mac) Grohmann & Campanha (IGc-USP) OpenStereo AGU 10 5 / 35
