Spherical projections with OSXStereonet

摘要: OSXStereonet is a Macintosh application to plot spherical data (lines, planes and small circles) in 2D, equal angle or area stereonets of any view orientation, 3D. The program can also operate on the calculating angles intersections between lines planes, (poles) from vice versa, performing rotations statistical analyses (cylindrical conical best fit, mean vectors contouring) data. stereonet most program's methods are based linear algebra. We illustrate functionality as well its close relation algebra concepts such transformations through several examples including down plunge projections, map calculations, stress orientations paleomagnetic reversal tests.
