Three-dimensional property ownership map base for smart urban land administration. This project aims to support smart urban land administration by upgrading a two-dimensional (2D) property ownership map base to a three-dimensional (3D) map base, using 3D digital data from regulatory subdivision processes. The map base coherently represents all land-based parcels, and provides valuable intelligence used to make land and property decisions. The 2D map base omits above and underground properties and infrastructure common in urban settings, forcing stakeholders to rely on fragmented data streams. The 3D map base will provide a connected, digital source of intelligence about urban property objects. This is expected to reduce social and economic risks and enable more intelligent city planning and management.Read moreRead less
Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estima ....Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estimate of the water vapour content must be accompanied by a realistic, reliable quality indicator. Such quality indicators are not currently attainable using existing GPS data processing methods, with this project aiming to overcome such deficiencies.Read moreRead less
A Marine Cadastre for Australia - Addressing Key Scientific and Policy Issues. A marine cadastre provides a means for delineating, managing and administering legally definable offshore boundaries. Marine cadastre research was initiated in Australia under a previous ARC grant which aimed at defining issues affecting the development of an Australian marine cadastre. The current project focuses on four such issues :

A marine cadastre provides a means for delineating, managing and administering legally definable offshore boundaries. Marine cadastre research was initiated in Australia under a previous ARC grant which aimed at defining issues affecting the development of an Australian marine cadastre. The current project focuses on four such issues :
(1) Resolving ambiguities in the definition of the tidal interface
(2) Issues in the use of natural rather than geometric boundaries to define jurisdictional limits
(3) Expanding the Australian Spatial Data Infrastructure to support a marine cadastre
(4) Legal and security issues intrinsic to the development of a marine cadastre.Read moreRead less
The Integration of Built and Natural Environmental Datasets in National Spatial Data Infrastructure Initiatives. Delivering sustainable development nationally assumes knowledge about the natural and built environment. This requires access to data about these two environments which is facilitated by establishing a National Spatial Data Infrastructure (NSDI).

Delivering sustainable development nationally assumes knowledge about the natural and built environment. This requires access to data about these two environments which is facilitated by establishing a National Spatial Data Infrastructure (NSDI). The problem in Australia is that the states are the custodians of large to medium built and natural datasets while the Federal Government is the custodian of small scale natural datasets. While Australia has seen some success, the integration of these datasets is hampered by jurisdictional, institutional, administrative and legal issues. This research will investigate the differences in these forms of data and the justification and policy framework to integrate them in a NSDI.Read moreRead less
Automating and integrating spatial data and metadata processes. The ability to automatically generate metadata relating to spatial information, and make it available through the Australian SDI will have important benefits not only at an organizational level (with each organization saving time and money in generating their metadata), but at a national level because it will assist delivery of high quality spatial information and services to vast areas of Australia. This will aid in addressing nati ....Automating and integrating spatial data and metadata processes. The ability to automatically generate metadata relating to spatial information, and make it available through the Australian SDI will have important benefits not only at an organizational level (with each organization saving time and money in generating their metadata), but at a national level because it will assist delivery of high quality spatial information and services to vast areas of Australia. This will aid in addressing national issues concerned with land management, environmental sustainability, water rights, indigenous land tenure and disaster management, which can only be addressed by having the ability to find and access high quality spatial information.

Sensor Integration for Low-Cost Robust Machine Automation. Machine automation (MA) radically improves efficiency of mining and construction operataions. When used for farming, it makes Australia more competitive with subsidised competitors in Europe and USA. In one case, a 50% reduction in tractor fleet resulted when night plowing was made possible using MA techniques. The systems developed in this project will make MA far more attractive to Australian agriculture, mining and construction indust ....Sensor Integration for Low-Cost Robust Machine Automation. Machine automation (MA) radically improves efficiency of mining and construction operataions. When used for farming, it makes Australia more competitive with subsidised competitors in Europe and USA. In one case, a 50% reduction in tractor fleet resulted when night plowing was made possible using MA techniques. The systems developed in this project will make MA far more attractive to Australian agriculture, mining and construction industries, by making it more robust and less susceptible to difficult conditions, such as under trees.Read moreRead less
Reconstructing land tenure maps of Australia in 3D. Existing land tenure maps of above and below ground, such as apartment ownership, tunnels, and mining, are maintained using 2D drawings. However, the drawings are not structured and valuable for detailed and advanced visualisation, analytics, and simulation, which are essential for testing potential interventions and policy development. This project aims to develop a data validation framework for transforming current drawings and reconstructing ....Reconstructing land tenure maps of Australia in 3D. Existing land tenure maps of above and below ground, such as apartment ownership, tunnels, and mining, are maintained using 2D drawings. However, the drawings are not structured and valuable for detailed and advanced visualisation, analytics, and simulation, which are essential for testing potential interventions and policy development. This project aims to develop a data validation framework for transforming current drawings and reconstructing them into 3D models. The outcomes include validation principles, formal mathematical terms, and computational algorithms. Benefits include a cost-effective onshore alternative to offshore 3D reconstruction practices, efficient land development and infrastructure planning, and fewer property disputes.Read moreRead less

The objective of this project is to investigate the issues and define the problems associated with the development of a marine cadastre, thereby providing the foundation for future research.Read moreRead less
Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. ....Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. Building on from earlier work by University of New South Wales, University of Adelaide and GPSat Systems, this project aims to create a system for locating interference and spoofers to GNSS of any power in real time, providing layered monitoring and reactive mitigation solutions against interference and spoofing attacks.Read moreRead less
Improved Geodetic Modelling through Very Long Baseline Interferometry. We plan to develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems, to produce an optimum, unified terrestrial reference system based on VLBI measurements, together with GPS/SLR data, especially for the Antarctic region.

We plan to develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems, to produce an optimum, unified terrestrial reference system based on VLBI measurements, together with GPS/SLR data, especially for the Antarctic region. The ITRF is based on the VLBI ICRF linking our astrometric and geodynamic research programs.
We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic effects, such as post-glacial rebound and tectonic motion, global mean sea level change and determine length-of-day (LOD) variations, focused primarily on understanding the contribution from the Southern Oceans.
