In 2014, the first version of the DOI minting software was produced,allowing machine to machine minting of DOIs. Written in Java, it accessed the GeoCat database for metadata, sent that to DataCite, and reinserted the returned DOI back into the database.

International Quiet Days (IQD's) are the days where the geomagnetic variations are a minimum in each month. International Disturbed Days (IDD's) are 5 days in each month where the geomagnetic variations are maximum. The classification of days is relative only to the month of calculation. The average disturbance level in one month may differ from another.

The ANZLIC Metadata tool uses the ISO 19139 (2005) metadata standard which is the current supported metadata standard used in Australia in its ArcGIS Desktop version 10.4 software package. This metadata tool is intended to be used through the ArcGIS Desktop version 10.4 software accessed via the description tab in ArcCatalog. The tool was previously developed and supported by Esri Australia but this was formally handed over to ANZLIC in 2017. Geoscience Australia in support of ANZLIC has developed this new metadata tool based on the previous work of Esri Australia and the new Esri Inc ArcGIS Desktop 10.4 Metadata toolkit. The tool is intended for users of Esri Inc ArcGIS Desktop version 10.4 software to create ANZLIC compliant ISO 19139 metadata associated with datasets.

Providing tropical cyclone best track data in a centralized location to aid our understanding of the distribution, frequency, and intensity of tropical cyclones worldwide.

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.

This software package is used to produce Bushfire Attack Level (BAL), a measure of the severity of a building's potential exposure to bushfire, based on Method 1 in Australian Standard AS 3959 (2009)--Construction of buildings in bushfire-prone areas.

The physical properties of non-porous basement rocks are directly related to the mineralogy of those rocks. The MineralMapper3D software package originally developed by Nick Williams at the Predictive Mineral Discovery Cooperative Research Centre (pmd*CRC), Geoscience Australia, uses the physical properties of minerals to provide bounds on estimates of the abundance of specified minerals in non-porous basement rocks. This approach is applicable to both estimates of density and magnetic susceptibility derived from 3D inversions of gravity and magnetic data as well as physical measurements on specimens or down-hole derived physical properties.
