SSPX calculates strain/strain rate from displacement/velocity data in 2D and 3D. SSPX works on problems such as computing strain rates from GPS data, computing finite strain in a discrete element model, or computing strain from displacements in an analogue model. Geographic data can be displayed in a Map/Satellite View. SSPX can also batch process sequential files. SSPX is a powerful tool to compute and analyse strain. NOTE: SSPX runs on OSX 10.9 +
