About the 3D Data Viewer

Geoscience Australia's 3D Data Viewer is an application developed using NASA's World Wind Java Software Development Kit (SDK) to display Australia's continental data sets. The viewer allows you to compare national data sets such as the radioelements, the gravity and magnetic anomalies, and other mapping layers, and show the data draped over the Australian terrain in three dimensions.

The viewer currently displays the following Geoscience Australia data layers:

• Radiometric Map of Australia
• Gravity Anomaly Map of the Australian Region
• Magnetic Anomaly Map of Australia
• Surface-related Uranium
• Terrain interpretations

Launching the application

The 3D Data Viewer application requires the Java Runtime Environment which most computers will already have installed. Clicking on the Launch the 3D Data Viewer link below will start the download of the application and the relevant software components from Geoscience Australia, NASA and Sun Microsystems websites. You may see a number of notices asking you to confirm these downloads and you will need to click the run/accept buttons to proceed. The NASA and Sun Microsystems notices should only be displayed the first time you launch the application.

• Launch the 3D Data Viewer

Requirements

The World Wind Viewer requires up-to-date video card drivers and the Java Runtime Environment.

• How to update video card drivers - especially for OpenGL support
  
• Download the latest Oracle Java Runtime Environment (JRE) - (JRE 6 or more recent required).
  

Known issues

Image download speeds will vary, depending on your internet connection.

A blank screen or a blank application window (ie. only displays the sky layer) is typically caused by out of date graphics drivers. Please update your drivers from the graphics card manufacturer via the links under Requirements above.
