The GPlates is a free and open-source application software, developed by a group of international scientists and software developers to simulate and visualize the Plate tectonics reconstruction process. The main contributors include the EarthByte group in the school of Geosciences at the University of Sydney, the Division of Geological and Planetary Sciences (GPS) at CalTech, the Geodynamics Team at the Geological Survey of Norway (NGU). GPlates is mainly used in plate tectonics reconstruction research and education. User manual and tutorial are available online.
