The HazImp system enables users to analyse the impact of natural hazards. HazImp is capable of assessing the impact of a range of hazards including, but not limited to, floods and tropical cyclones. HazImp uses a set of pre-processed inputs, perform logic based analysis using predefined models and produce a range of quantitative outputs. These inputs may be produced by existing external systems including hazard modelling applications. HazImp outputs may include aggregated values, statistical figures, diagrams and spatial maps to describe the impact of the natural hazard to the study area. HazImp assesses the impact of a natural hazard as a combination of three fundamental elements: • Hazard - the type of hazard and its properties; • Exposure - elements that are or could be subject to the hazard; • Vulnerability – an element’s physical or social susceptibility to the hazard. All three elements are required to properly assess the impact of a hazard and a change in any element will affect the impact results. HazImp supports a set of inputs, each corresponding to one of these three elements. HazImp is designed to support a wide variety of scenarios making it highly customisable to the event or events being analysed. In particular, HazImp is compatible with existing GA systems. HazImp supports two primary business cases for natural hazard impact assessment. The first, to support risk assessment and mitigation where system response times can be generous and could be as long as weeks. The second, is forecasting the impact of an imminent event, where an assessment is needed in real-time.

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 Geoscience Australia World Wind Suite is a suite of tools built around the NASA World Wind Java SDK including the World Wind Data Viewer and Animator tools. The tool suite has been released as open source under the Apache 2.0 license and is available through Github (http://www.ga.gov.au/ga-m3dv/ga-worldwind-suite). Individual products in the suite are catalogued individually under IDs 69165 and 73044.

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.

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 suite has been under development since 1969 and is stored as a file system under /nas/pmd/prg/. It consists of source code for geophysical software written for processing tasks which cannot be accomplished using commercially licensed software accessible to GA. The majority of this software is written in Fortran, Perl, Python, awk and Visual Basic programming languages designed to run on Unix, Linux, Windows and Vax/VMS operating systems. At the date of this entry the collection has 1390 inventoried computer programs and 263,000 lines of code. The source code contains standardised headers following guidelines developed by GA's Programmer User Group (and fits with ISO 19115), and this allows the collection to be discovered and delivered via a web-based seach tool (see links). Current contributors are listed as authors of this metadata entry, however past employees and others are noted with the standard author header for each item of software.
