StrainTool: A software package to estimate strain tensor parameters

Dr. Dimitrios G. Anastasiou; Xanthos Papanikolaou; Dr. Athanassios Ganas; Prof. Demitris Paradissis

StrainTool allows the estimation of Strain Tensor parameters, on the Earth's crust, given a list of data points, aka points on the Earth along with their tectonic velocities. Also provided are output parameters related to the plotting of strains/strain-fields using the Generic Mapping Tools software (http://www.soest.hawaii.edu/gmt/ ). 

The algorithm to calculate horizontal strains (or strain rates) through interpolation of GNSS velocities is based on the Shen et al (2015) method (doi: 10.1785/0120140247) This software package has received funding from the European Union's Horizon 2020 research and innovation programme EPOS under grant agreement N°676564
