  • Take a journey through time! This app will guide you along the Geoscience Australia TimeWalk, leading you on a 1.1 kilometre journey through the Earth's 4600 million year (Ma) history. The TimeWalk is a physical representation of the evolution of the Earth from its formation to the present day. Large rock samples collected from around Australia are on display along the TimeWalk, at designated locations that reflect their age of formation. Each rock has a story to tell, with geological, economic, environmental and/or cultural significance. Use this app to read, hear and learn all about the significance of these rocks and their relevance to Earth's history. Plus, discover other facts and events of geological history along the way! The TimeWalk is located in the landscaped gardens at the front of the Geoscience Australia building, at the corner of Jerrabomberra Ave and Hindmarsh Drive, Canberra, Australia.

  • Geodetic Calculations - Redfearn's Formulae, Geographic to Grid Given Latitude and Longitude, calculate Easting, Northing, Zone for a Universal Transverse Mercator (UTM) projection, Grid convergence and Point Scale Factor.

  • Redfearne's Formulae Excel spreadsheet

  • AUSPOS provides users with the facility to submit dual frequency geodetic quality GPS RINEX data observed in a 'static' mode, to our GPS processing system and receive rapid turn-around Geocentric Datum of Australia (GDA) and International Terrestrial Reference Frame (ITRF) coordinates.

  • Currently a number of different landslide inventories exist in various databases within Australia, and each uniquely addresses a specific purpose. These databases range in scale and detail, and although some similarities and a number of common themes are apparent between databases, the method in which information is organised and described varies considerably.

  • This application allows the user to see a `real-time' representation of the Earth from a satellite that is currently orbiting our planet. The satellite database that provides the positioning information is updated regularly, but may not reflect the current position of satellites that manoeuvre frequently after reaching orbit.

  • Australian Regional GPS Network Updates Periodically, changes are made to the ARGN site's equipment or processes, to continually improve the system, to implement new technology, or to overcome problems. Where appropriate, these changes are reflected in the site logs. Also, while every endeavour is made to avoid them, occasionally there are delays or gaps in the data supply, due to circumstances beyond our control (such as floods, fires, mice plagues, lightning strikes and other minor incidents). When any significant events of this type occur, an Email is sent to everyone on the ARGN mailing list, giving the current status. If you wish to be notified of these events, please fill in the form below.

  • If you felt an earthquake, or know of an earthquake that occurred recently, please fill in this form. Even if you did not feel the earthquake yourself, please fill in the form, as this information will assist us.

  • Rock properties provide the vital link between observed geophysical data and interpreted geology. Geoscience Australia has periodically made measurements of rock properties to support various investigations into the composition and structure of the subsurface. The Rock Properties Project consolidates this information into a single database structure and makes it accessible to external clients via a web delivery application. We have chosen to initially concentrate on mass density and magnetic properties, as these are of prime importance to the important gravity and magnetic datasets maintained for the Australian region by Geoscience Australia. Additional property types and more extensive datasets will be added over time.

  • Using data from the six Australian continental magnetic observatories, a contour display of the rate-of-change of magnetic total intensity, F, over the continent is shown below. This provides a broad view of how F changes across Australia. The units shown on the contours are in nanoTesla per hour. The grey squares indicate the locations of the magnetic observatories. Both real-time and historic data can be displayed in this format. All maps are generated from a period of 15 minutes of observatory data and available at 15 minute intervals.
