The estimation of Euler pole parameters has always been an important issue in global tectonics and geodynamics studies. In addition, the increasing number of permanent GPS stations and the ease of access to their data, along with advances in computers, promise new methods and tools for the estimation and the quantitative analysis of Euler pole parameters. Therefore, I developed the Euler pole calculator software using a set of mathematical algorithms based on the model of tectonic plate motion on a spherical surface. The software is able to calculate the expected velocities for any points located on the earth’s surface given the relevant Euler pole parameters and to estimate the Euler pole parameters given the observed velocities of a set of sites located on the same tectonic plate.

I developed the software using the MATLAB programming language with a Graphical User Interface. Therefore the software is cross-platform and can be run under the majority of operating systems(Windows, Macintosh and Unix/Linux). It requires the basic MATLAB as well as Statistics and Mapping toolboxes. You can find a complete discussion about mathematical algorithms and functions of the software in this paper.
EPC is available as an open source software program under the BSD license. The source code can be downloaded from the software home page at SourceForge and also at the GPS Toolbox website. The software was developed in the hope that it will be useful. Even though, it was already tested and correct functionality was assured, it is published as it is (WITHOUT ANY WARRANTY).
