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

Integrated GPS and interferometric SAR techniques for ground subsidence monitoring. The Global Positioning System (GPS) is commonly used for measuring ground subsidence due to underground mining and similar activities. However, GPS techniques cannot easily survey a dense enough grid of points to monitor subsidence across a wide area. This project aims to densify the GPS field measurements with the interferometric processing of Synthetic Aperture Radar (SAR) images. The outcomes of this research ....Integrated GPS and interferometric SAR techniques for ground subsidence monitoring. The Global Positioning System (GPS) is commonly used for measuring ground subsidence due to underground mining and similar activities. However, GPS techniques cannot easily survey a dense enough grid of points to monitor subsidence across a wide area. This project aims to densify the GPS field measurements with the interferometric processing of Synthetic Aperture Radar (SAR) images. The outcomes of this research include optimal integration models, operational software systems and quality-control measures. A test area south of Sydney, where subsidence caused by underground coal mining is having significant detrimental effect on surface infrastructure, will be monitored over a three-year period.Read moreRead less
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.
