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.
The Rock Properties Explorer is the discovery and delivery tool for Geoscience Australia's Rock Properties Database. This database contains a range of petrophysical data from around Australia including mass density, magnetic susceptibility and natural magnetic remanence of surface and borehole samples.
View information on or download scanned images of all 1:250 000 scale geology maps of Australia in the AUSGIN Geoscience Portal. The images are available in 125 DPI and 250 DPI resolution JPG files. These images include the full map surrounds and legends, and are not georeferenced. For full instructions, consult the user guide for the Geoscience Portal.
Compute Sun and Moon Azimuth & Elevation To use this facility you need to know the latitude and longitude of the location for which you want to calculate the azimuth and vertical angle.
Computes sunrise, sunset and twilight times using the National Gazetteer of Australia.
Interactive topographic map indexes for 1:50 000, 1:100 000, 1:250 000 and 1:1 million scale.
Topographic Data and Map specifications for The National Topographic Database and NTMS series 1:250 000 and 1:100 000 scale topographic map products.
Geodetic Calculations - Vincenty's Formulae, Direct Method Given the latitude and longitude of a point (1) and the forward geodetic azimuth (1-2) and ellipsoidal distance to a second point (2), calculate the latitude and longitude of the second point and the reverse azimuth (2-1).
Geodetic Calculations - Vincenty's Formulae, Inverse Method Given latitude and longitude of two points, calculate the ellipsoidal distance and forward and reverse azimuths between the points.
As part of the National Flood Risk Information Project, Geoscience Australia will map flooding from satellite imagery across Australia from 1987 to the present.
