GPlates

GPlates is open-source application software offering a novel combination of interactive plate-tectonic reconstructions, geographic information system (GIS) functionality and raster data visualisation.

The GPlates software platform comprises the GPlates desktop software, command line tools, GPlates Python library (pyGPlates), GPlates web service and web application, a high-level Python encapsulation package GPlately, a plate tectonic toolkit PlateTectonicTools and a data server which serves plate reconstruction model datasets from the cloud. GPlates also supports integration with GeoServer and PostGIS databases.

By incorporating this technology stack, GPlates simplifies and streamlines data processing, integration, analysis, and visualisation to ease the workload for geoscientists. The software can be used to create new plate reconstruction models or optimize existing models.

History
GPlates was conceived in 2002 by the following committee:
 * Dietmar Müller [committee chair] (University of Sydney)
 * Stuart Clark (University of Sydney)
 * Mike Coffin (ORI/IFREE)
 * Mike Gurnis (Caltech)
 * Lawrence Lawver (PLATES/UTIG)
 * Louis Moresi (Monash University/VPAC)
 * Tim Redfield (PGP/NGU)
 * Walter Roest (GSC)
 * Trond Torsvik (PGP/NGU)

The first GPlates prototype ("GPlates 0.5") was released on 30 October, 2003. The first stable version GPlates 1.0.0 was released in 2010. The latest release is GPlates 2.3 and was released in September 2021.

In 2012, the GPlates team won the NeCTAR/ANDS #nadojo competition. And in the same year, the GPlates team started the development of GPlates Portal and Web Service. In 2014, the GPlates Web Portal and Web Service were launched.

In 2016, the first public version of pyGPlates was released. The pyGPlates beta revision 28 was released on 8 August 2020. This is the first version which supports Python3. The latest pyGPlates release is 0.36 and was released in May 2022.

In 2022, the first version GPlately was released. The latest GPlately release is 1.0.0 and was released in April 2023.

After keeping source code on Apache Subversion and SourceForge for nearly 20 years, the GPlates source code was moved to GitHub on 1 August, 2023.

Functionality
GPlates enables both the visualization and the manipulation of plate-tectonic reconstructions and associated data through geological time:
 * Load and save geological, geographic and tectonic feature data.
 * Assign feature data to tectonic plates.
 * Reconstruct feature data to past geological times.
 * Query and edit feature properties and geometries.
 * Modify reconstructions graphically.
 * Visualize vector and raster data on the globe or in one of the map projections.
 * Visualize sub-surface 3D scalar fields as isosurfaces or 2D cross-sections.
 * Export reconstructed data as a time-sequence of exported files.
 * Use plate polygons (with dynamic boundaries and deformation) to calculate velocity fields.

Contributors
GPlates is developed by an international team of scientists and professional software developers at: with past contributions from:
 * the EarthByte group in the school of Geosciences at the University of Sydney
 * the Division of Geological and Planetary Sciences (GPS) at Caltech
 * the Centre for Earth Evolution and Dynamics (CEED) at the Department of Geosciences, University of Oslo, Norway
 * the Geodynamics Team at the Geological Survey of Norway (NGU)

Adoption
GPlates is used by geophysicists, students and researchers in academic institutions, government departments and industry. It has also gained currency in the creative worldbuilding community as a tool for maintaining realism or verisimilitude in geographic features. In 2019, two Australian researchers used the software to create a tectonic map of the continents within the fictional Game of Thrones universe.

Implementation
GPlates runs on Mac OS X, Microsoft Windows and Linux. GPlates is written in C++ and uses OpenGL to render its 3D globe and 2D map views. It uses Qt as a GUI framework. The Boost C++ library has also been widely used. Other libraries include GDAL, CGAL, proj, qwt and GLEW.

GPlates uses the GPlates Geological Information Model (GPGIM) to represent geological data in a Plate tectonics context. The GPlates Markup Language (GPML) is an XML implementation of the GPGIM derived from the Geography Markup Language (GML).

Licensing
GPlates is released under GNU General Public License version 2.0 (GPLv2) and the source code can be found on SourceForge.

GPlates Python Binding
The GPlates Python library (pyGPlates) enables access to GPlates functionality via the Python programming language. It allows users to use GPlates in a programmatic way and aims to provide more flexibility than the GPlates desktop interface can offer. The pyGPlates is available on Conda (conda-forge channel). The latest pyGPlates release is 0.36 which was released on 06 May, 2022.

GPlates Web Service
The GPlates Web Service was built upon pygplates. It allows users to access the GPlates functionalities via Internet. The GPlates Web Service has been containerized. Users can deploy the Docker container locally to enhance performance and data security.

GPlately
The GPlately Python library is a high-level encapsulation of pygplates and PlateTectonicTools. It was created to accelerate the spatio-temporal data analysis. GPlately is available on PyPI and Conda (conda-forge channel). The latest GPlately release is 1.3.0 which was released on 22 December, 2023.

GPlates Portal
The GPlates Web Portal is a gateway to a series of GPlates-based web applications. Initially the portal was hosted on Nectar Cloud. Later on, it was migrated to Amazon Elastic Compute Cloud. Below is a list of applications in GPlates Web Portal.
 * Vertical Gravity Gradient
 * 3D visualization of the Vertical Gravity Gradient Grid.


 * Raster Reconstruction
 * Reconstruct raster images through time.


 * Paleomap Maker
 * Data reconstruction and visualization service.


 * Dynamic Topography
 * IPython Sandbox
 * Demonstrate how to use pyGPlates in IPython Notebook.


 * Magnetic Picks
 * SRTM15_PLUS Topography
 * Seafloor Lithology

The Cesium JavaScript library is used to render the 3D globe in a web browser.

GPlates Data
The "SampleData" was made available along with very software releases. Since GPlates release 2.2 the "SampleData" underwent rebranding and is now known as "GeoData". More GPlates-compatible data can be found on Research Data Australia which is the data discovery service of the Australian Research Data Commons (ARDC).
