An Integrated Ground Deformation Monitoring System Based on the Integration of InSAR, GPS and GIS Technologies. Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor ground deformation at high spatial resolution. When integrated with Global Positioning Systems (GPS) so that atmospheric disturbance in InSAR result can be corrected, deformation can be resolved at sub-centimetre accuracy. The corrected InSAR result can be exported as a data layer into Geographic Information System ....An Integrated Ground Deformation Monitoring System Based on the Integration of InSAR, GPS and GIS Technologies. Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor ground deformation at high spatial resolution. When integrated with Global Positioning Systems (GPS) so that atmospheric disturbance in InSAR result can be corrected, deformation can be resolved at sub-centimetre accuracy. The corrected InSAR result can be exported as a data layer into Geographic Information Systems (GIS) for further analysis. In collaboration with Hong Kong Polytechnic University researchers, the integrated InSAR-GPS-GIS system will be tested in both Hong Kong and Australia. The expected outcomes include a suite of algorithms and software tools capable of operational, cost-effective ground deformation monitoring.Read moreRead less
Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and respo ....Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and responsibilities in the marine environment. 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
Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from ....Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from the coast and also suffers from regionally correlated biases. This project proposes to address these problems through re-tracking radar altimetry waveforms to derive new data in the coastal margin, enabling the production of new inferences on sea-level change and extremes at dramatically improved spatial resolution around Australia.Read moreRead less
Remote Sensing Based on Indirect GPS Signals. It is intended to utilize signals from the GPS satellite system, reflected from stationary objects (walls and water surfaces), to detect deformation or changed surface characteristics using the bistatic radar principle. The GPS receiving system consists of one or more signal detection components with antennas, as well as a processing device. The main objectives of the research are: the estimation of the power budget, developing techniques for system ....Remote Sensing Based on Indirect GPS Signals. It is intended to utilize signals from the GPS satellite system, reflected from stationary objects (walls and water surfaces), to detect deformation or changed surface characteristics using the bistatic radar principle. The GPS receiving system consists of one or more signal detection components with antennas, as well as a processing device. The main objectives of the research are: the estimation of the power budget, developing techniques for system modelling, developing techniques for simultaneous reception of signals from different satellites, and processing these signals with the aim of improving the spatial resolution, development of a demonstrator system, and evaluation of the system for selected remote sensing tasks.
