OSXStereonet plots lines and planes in a stereographic, equal angle or equal area, projection. The program can produce various types of plots such as scatter plots of lines, great circle plots of planes, contour diagrams of lines, rose diagrams, stereonets viewed from any orientation, and plots of latitude-longitude data (e.g. coastlines).
In addition, the program can perform various operations on data, including calculating poles to planes, rotation of planes and lines, constraining lines to lie on respective planes, mean vector, cylindrical best fit, and conical best fit to a distribution of lines, and angle between lines and planes.
OSXStereonet is a revamp Cocoa version of the popular Stereonet program by Richard Allmendinger. OSXStereonet has the same functionality as Stereonet, but in addition it has advantages such as a faster and more intuitive interface to work with data, multiple lines and planes datasets and multiple documents, and great speed and graphics.
