This application allows the user to guess what cities are indicated by the satellite images.

AUSGeoid98 is the current model in a series of national geoid models for Australia produced by Geoscience Australia. It replaced AUSGeoid93 and uses the latest available data and techniques.

The GNSS database contains metadata and data quality statistics for continuous operating GNSS stations in Australia, its Territories and the South Pacific. GNSS stations consist of permanent geodetic quality GPS receivers, on geologically stable marks, with eight stations within Australia known as the Australian Fiducial Network (AFN) . These stations provide the geodetic framework for the spatial data infrastructure in Australia and its territories. They also provide input for the measurement of earth processes, such as crustal dynamics and sea level rise. Data from the GNSS network also contributes to the International GNSS Service . Where stations are managed by Geoscience Australia, Rinex data and quality statistics are available from this website.

The earthquake mapping tool allows you to: * view recent earthquakes which occurred over the past 30 days * search and explore all Australian earthquakes * search and explore earthquakes worldwide * view seismograms of earthquakes over the past 90 days * advise Geoscience Australia when you have felt a recent earthquake.

This application provides quick-look images and download options of the MOD43 Nadir BRDF-Adjusted Reflectance (NBAR) Products generated by ACRES. These products are a composite, generated for MODIS spectral bands 1-7 at the mean solar zenith angle over a 16 day period. In addition to the NBAR composite products, the BRDF parameters for each band, the ancillary, and band quality information are also provided. Each NBAR composite product is in GeoTIFF format at 500 metres resolution. All of the files are compressed using gzip/tar as "*.tar.gz". For Windows gzip/tar support please try WinZip.

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.

Natural hazards have an impact on every Australian State and Territory. These hazards include bushfires, cyclones, earthquakes, floods, landslides, severe weather, tsunami and volcanoes. These phenomena threaten lives and damage private and public assets, as well as disrupt water, power, transport and communication services. These hazards and their associated impacts also can seriously affect employment, public administration and incomes to industry, agriculture and commerce.

This system provides magnetic, radiometric, gravity and digital elevation data from Australian National, State and Territory Government geophysical data archives.

Compute Moonrise and Moonset Times To use this facility you need to know the latitude and longitude of the location you want to calculate rise and set times for. There are several ways you can determine this:
