pygplates beta revision 12 released

GPlates Vector Logo

GPlates Vector LogoThe first beta release of pygplates (the GPlates Python library) is now available for download.

pygplates enables access to GPlates functionality via the Python programming language. This may be of particular use to researchers requiring more flexibility than is provided by the GPlates user interface.

The following pygplates functionality is available:-

  • Load and save feature data (GPML, Shapefile, etc)
  • Create/modify/query feature data
  • Traverse/modify/query plate rotation hierarchy
  • Partition into plates and assign plate properties
  • Reconstruct geometries, flowlines, motion paths
  • Resolve topological plates and query their boundary sections (ridges/subductions)
  • Calculate velocities
  • Distance between geometries (region-of-interest queries)
  • Geometry queries (length, point-in-polygon, area, centroid, tessellate, interpolate, join, partition)

Abstract
We present a revised global plate motion model with continuously closing plate boundaries ranging from the Triassic at 230 Ma to the present day, assess differences between alternative absolute plate motion models, and review global tectonic events. Relatively high mean absolute plate motion rates around 9–10 cm yr-1 between 140 and 120 Ma may be related to transient plate motion accelerations driven by the successive emplacement of a sequence of large igneous provinces during that time. … Read more…

Opal exploration research recognised as outstanding highlight

Recent EarthByte research on opal exploration was recognised as an outstanding highlight and reflects the work of many of the group including, Andrew Merdith, Tom Landgrebe, Adriana Dutkiewicz and Patrice Rey. Congratulations to all of the contributors to the project and specifically to John Cannon and Michael Chin, the GPlates developers!
