    1. Introduction to GPlates 1.1. The Aim of this Manual The GPlates user manual aims to provide the reader with an almost complete understanding of the operations, applications and manipulations within GPlates software. The manual is divided into chapters based on function and tasks. For example, a step-by-step guide to loading data into GPlates can be found in Loading and Saving; an overview of editing the geometries of features can be found in Editing Geometries. 1.2. Introducing 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. 1.2.1. 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. 1.2.2. The Goals of GPlates 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.
    1.3. GPlates Development GPlates is developed by an international team of scientists, professional software developers and post graduate students at: the EarthByte Project (part of the AuScope National Collaborative Research Infrastructure Strategy (NCRIS) Program) in the School of Geosciences at the University of Sydney (under the direction of Prof. Dietmar Müller) the Division of Geological and Planetary Sciences at CalTech (under the direction of Prof. Michael Gurnis) the Centre for Geodynamics at the Norwegian Geological Survey (NGU) (under the direction of Prof. Trond Torsvik). Collaborating scientists at the University of Sydney, the Norwegian Geological Survey and CalTech have also been compiling sets of global data for plate boundaries, continental-oceanic crust boundaries, plate rotations, absolute reference frames and dynamic topography. GPlates is free software (also known as open-source software), licensed for distribution under the GNU General Public License (GPL), version 2. 1.4.

    2. Introducing The Main Window This section describes the Main Window, the heart of the GPlates user interface. Below we present annotated screenshots of GPlates, label the key areas of the window, and provide a brief overview of each. 2.1. The Main Window When you start GPlates, the first window you will encounter is the Main Window. This contains your view of the globe, and is the starting-point of all tasks within GPlates. It is here that you can control your view of the globe, choose your reconstruction time, load and unload data, and interact with geological features. Item 1 2 3 4 5 6 7 8 Name Menu Bar Tool Palette Time Controls Animation Controls Zoom Slider Task Panel View Control Camera Coordinate Description This region of the Main Window contains the titles of the menus. A collection of tools which are used to interact with the globe and geological features via the mouse pointer. A collection of user-interface controls for precise control of the reconstruction time. A collection of tools to manipulate the animation of reconstructions. A mouse-controlled slider which controls the zoom level of the Globe View camera. Task-specific information and controls which correspond to the currently-activated tool. Controls which projection is used to display data and the exact zoom level as a percentage. An information field which indicates the current globe position of
    8 9 10 Camera Coordinate Mouse Coordinate Clicked Geometry Table An information field which indicates the current globe position of the Globe View camera. An information field which indicates the current globe position of the mouse pointer. Displays a summary of each geometry or feature touched by the last mouse click. The appearance of the Main Window - particularly the layout of the different window components - will change as GPlates continues to evolve. 2.2. Reconstruction View The reconstruction view provides the user with a display of their data on the GPlates globe or map reconstructed to a moment in time. Control of the current reconstruction time, is located under the menu bar on the left, (see image below). The time can be controlled by both a text field, forwards and backwards time buttons, and the animation slider. In addition the shortcut Ctrl+T to enter a time value in the text field. 2.2.1. Camera Control Drag Globe tool is activated the GPlates globe can be re-oriented freely using the mouse with a simple When the click and drag motion. If another tool is selected the globe can still be dragged by holding down Ctrl. If the user wishes to adjust the camera position to a particular latitude and longitude, pressing Ctrl+L will pop up a window allowing manual entry of coordinates. The amount of camera zoom can be controlled by the following: Zoom In via mouse-wheel up. Zoom Out via mouse-wheel down. Zoom Control field allowing direct entry of percentage value (between 100% and 10000%). Click the text field, type in a new value and press Enter to change the zoom. Zoom Slider, which works on a power scale. Keyboard shortcuts: use the + and - keys to zoom in and out, and the 1 key to reset the zoom level to 1:1 (100%) scale. The position of the camera and mouse pointer are provided along the bottom of the reconstruction view.
    2.3. The Menu Bar Each item in a menu is an operation. Related operations are grouped into menus, with the menu title indicating the common theme. For example, the View Menu in the image below contains operations which manipulate the user’s view of the globe. Within a menu, similar operations are grouped visually by horizontal lines or within sub-menus. In the View Menu below, the Camera Location, Camera Rotation, and Camera Zoom controls are grouped into their own sub-menus. In the Layers Menu and Geometry Colours sub menu, check boxes are displayed to switch or choose operations. For example; Show Background Raster and the different colouring options are be activated by a small cross or tick that will be displayed in the box in the menu when selected.
    2.4. Tool Palette The Tool Palette is used to control your view and interaction with the GPlates globe and maps. You may recognise the concept of tools from graphics editing software (e.g. drawing tools in Photoshop ) or GIS software (e.g. ArcGIS mapping tools). The Tool Palette includes camera positioning tools, feature selection tools and drawing tools. A tool is activated by clicking on it; only one tool can be active at any time. The task panel will reflect the current tool that is activated.
