Dear all,
For information of those interested in the free GPlates plate tectonic reconstruction software, two software updates have recently been released and are available for download (http://www.gplates.org).
GPlates 1.5 is the stable release that adds the following new functionality:
- Project Files: Sessions can be saved and later restored
- New kinematics tool:
Displays table of latitude, longitude, velocity, and velocity-related quantities for a given lat-lon point, plate ID, and range of times.
Displays graph of above quantities against time.
Exports table to text file.
Kinematic tool settings dialog to change details of the velocity calculations.
Kinematic tool settings are saved in user preferences.
Auto-fills point data from focussed feature.
Auto-fills time ranges from animation settings.
- Compatibility with GeoJSON files for import or export to GPlates.
GPlates 1.5+Hellinger: is the experimental release, currently in testing phase
- Includes all 1.5 functionality as well as a Hellinger Tool.
- The tool uses segmented magnetic pick data points to find the best-fitting pole of rotation, known as Hellinger method.
Hellinger functionality:
Import and export data files compatible with the FORTRAN programs of Chang and co-workers.
Edit and create magnetic pick data points, via the canvas or tabularly via the Hellinger dialog.
Adjust segmentation of magnetic picks.
Enable/disable magnetic picks from inclusion in the fitting algorithms.
Specify pole and angle estimates via the canvas or via the Hellinger dialog.
Perform fitting using a Python implementation the FORTRAN programs.
Visualise resulting fit and uncertainty on the canvas.
Export fit and uncertainty data to text file.
Further information and download links are available at http://www.gplates.org
There is a newsletter explaining new functionality and recent sample datasets and rasters for use in GPlates available here:

Apologies for cross-posting.
