The main window of the EPC software version 2 |
The new version comes with a couple of new features, bug fixes, and improvements, as follows:
New features:
- Origin Rate Bias (ORB) is read and estimated in the direct and inverse Euler pole problems, respectively.
- The scatter plot of the residuals are now plotted in a separate window.
Bug fixes:
- Tab order in the 'Euler Pole Parameters' panel was fixed.
- Rotation matrix in the 'topocentric2geocentric' function was corrected.
- Formula for calculating WRMS was corrected.
- The position or coordinates text box is now active and shows the current position of the mouse cursor over the map canvas.
General improvements:
- The release date of the software is printed in the welcome message at the command line and in the 'About' window (Help>About).
- The plot canvas from the lower right of the main window was removed.
- Sub-menu names changed under 'Calculate' menu: 'XYZ to LLO' changed to 'EPP XYZ to LLO', and 'LLO to XYZ' to 'EPP LLO to XYZ'.
- Added the 'Ctrl+S' shortcut for the 'File>Save...' menu.
- Added two new indicators in the status bar for 'ORB' and 'Nominal Sigma'. They can be set from 'File>Settings...' menu or by clicking on the indicators.
- Estimated velocities (output table) is now saved in scientific notation.
- 'WRMSE' changed to 'WRMS' in the main window.
Like previous versions, EPC version 2 is also available as an open source software program under the BSD license. The source code can be downloaded from the software home page at SourceForge. I am preparing a manuscript for publication to explain the new mathematical models implemented in the software as well as the results of estimating and evaluating the Euler pole parameters for NATRF2022. Stay tuned!
