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.

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.

This is a CD rom that enables users to obtain relevant information on how to invest in mineral exploration within Australia.
