GPlates is desktop software for the interactive visualisation of plate-tectonics.

Santa LOVES His Copy! A Software Santa Pick! This works on the Early 2008 Mac Pro! Another fine educational toy from the Elves over at Source Forge!

GPlates is desktop software for the interactive visualisation of plate-tectonics.

GPlates offers a novel combination of interactive plate-tectonic reconstructions, geographic information system (GIS) functionality and raster data visualisation. GPlates enables both the visualisation and the manipulation of plate-tectonic reconstructions and associated data through geological time. GPlates runs on Windows, Linux and MacOS X.

GPlates is free software (also known as open-source software), licensed for distribution under the GNU General Public License (GPL), version 2.

What is GPlates?

GPlates is desktop software for the interactive visualisation of plate-tectonics.

GPlates offers a novel combination of interactive plate-tectonic reconstructions, geographic information system (GIS) functionality and raster data visualisation. GPlates enables both the visualisation and the manipulation of plate-tectonic reconstructions and associated data through geological time. GPlates runs on Windows, Linux and MacOS X.

What is a plate-tectonic reconstruction?

The motions of tectonic plates through geological time may be described and simulated using plate-tectonic reconstructions. Plate-tectonic reconstructions are the calculations of the probable positions, orientations and motions of tectonic plates through time, based upon the relative (plate-to-plate) positions of plates at various times in the past which may be inferred from other data. Geological, geophysical and paleo-geographic data may be attached to the simulated plates, enabling a researcher to trace the motions and interactions of these data through time.

The goals of GPlates are:

    * to handle and visualise data in a variety of geometries and formats, including raster data
    * to link plate kinematics to geodynamic models
    * to serve as an interactive client in a grid-computing network
    * to facilitate the production of high-quality paleo-geographic maps.

The GPlates program is accompanied by royalty-free data. Work is currently underway on a comprehensive user manual.
What can GPlates do?

As of GPlates 0.9.4, GPlates functionality includes:

    * loading and saving data:
          o loading geological feature data from the following formats:
                + GPML / compressed GPML
                + Plates4 line-format
                + ESRI Shapefile (including the ability to map shape attributes in a Shapefile to feature properties in GPlates on a user-specified, per-Shapefile basis)
          o loading reconstruction poles (finite rotations which enable geological features to be reconstructed through geological time) from the following formats:
                + GPML / compressed GPML
                + Plates4 rotation-format
          o loading raster images in JPEG format, including time-sequences of raster images, to enable visualisation of “gridded” geophysical data such as mantle density anomalies, mantle convection-driven dynamic surface topography and the crustal age or spreading rate of the ocean floor —
                + both global raster images, which are assumed to cover the whole globe, from -180 to +180 degrees longitude and -90 to +90 latitude
                + and smaller rasters with a user-specified surface extent
          o saving geological feature data in the following formats:
                + GPML / compressed GPML
                + Plates4 line-format
                + GMT “xy” format, with a variety of options for headers
          o saving reconstruction poles in the following formats:
                + GPML / compressed GPML
                + Plates4 rotation-format
    * viewing data in a graphical display:
          o displaying a 3-D orthographic projection of geological, geographic and tectonic features, and raster images, on the globe
          o reconstructing features to a desired geological time-instant, or animating over a period of geological time
          o moving and re-orienting the camera (the viewpoint of the user), by “dragging” the mouse on the globe, using the keyboard arrow keys, or specifying the desired viewpoint in a dialog box
          o zooming the camera, using the scroll-wheel of the mouse, the click-to-zoom tool, the slider on the right-hand-side of the reconstruction view, or the zoom buttons in the toolbar
          o choice of different colouring schemes for features
          o exporting a 2-D geometry snapshot of the current orthogonal-projected contents of the reconstruction view in Scalable Vector Graphics (SVG) format, for later viewing in a web-browser or vector-graphics editor such as Adobe Illustrator
    * interacting with features graphically:
          o choosing a feature, to query or edit its properties, by clicking upon its displayed geometry
          o digitisation of new geometries for the creation of new features
          o modifying the geometry of a feature interactively by dragging vertices
    * tabular display of data:
          o listing tables of reconstruction poles (finite rotations) for the current reconstruction time:
                + relative and equivalent rotations for each plate
                + a tree-like representation of the rotation hierarchy
                + the circuit between any plate and the stationary reference frame
          o exporting tables of reconstruction poles in CSV (comma-separated value) format, for later viewing in a spreadsheet such as Microsoft Excel.
          o listing tables of Shapefile attributes on a per-file basis, with one attribute per column
    * modifying reconstructions graphically:
          o manipulation of reconstruction poles by dragging the mouse cursor to move plates

What's next in GPlates?

We are currently working on the following functionality:

    * interactive graphical manipulation of the geometry of a feature (in a manner similar to that provided by a typical vector-graphics application)
    * a variety of map-projections (in addition to the current 3-dimensional orthographic projection of the globe)
    * interactive plate-boundary closure, enabling GPlates to generate plate-tectonic boundary conditions for geodynamic models in software such as:
          o the widely-used, open-source, spherical mantle convection package CitComS
          o the next-generation AuScope-funded spherical mantle convection package Underworld

Future functionality will include:

    * editing total reconstruction poles and sequences (in tabular form)
    * saving data in Shapefile format
    * calculating velocity fields using plate-reconstructions
    * layers
