SSPX

SSPX is a full fledged inverse modelling program to calculate best fitting strain tensors given displacement or velocity vectors in two or three dimensions. SSPX works equally well on small deformation problems such as computing strain rates from GPS data, or large deformation problems such as computing total strain in a highly deformed discrete element model (DEM). SSPX can process single files, or batch process sequential files. Data with lat-long information (e.g. GPS stations) can be plotted on a Map/Satellite view. SSPX was made for geologists, but it can be used by anyone interested in computing strain/strain rate from displacement/velocity data.
