Spatial data mining with intelligent agents for E-commerce. The current explosion of spatial data enables many new kinds of queries, but also raises technical issues. This project investigates such questions for online spatial data mining within the NSW Land and Property Information. The LPI will place its cadastral and land title information online during 2001 and plans to develop links to outside data holdings.

The current explosion of spatial data enables many new kinds of queries, but also raises technical issues. This project investigates such questions for online spatial data mining within the NSW Land and Property Information. The LPI will place its cadastral and land title information online during 2001 and plans to develop links to outside data holdings. These activities raise three key questions, with widespread relevance to other systems: finding practical approaches to processing queries in a distributed data warehouse; using adaptive agents to create robust, flexible spatial query systems; and identifying organizational models for commercialization of online spatial queries.Read moreRead less
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

Also, community oriented benefits will be seen through the improved prospects for new public-good applications of CRP, ranging for example from cultural heritage recording through to homeland security and forensic measurement for crime scene analysis.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

The capabilities of Quickbird imagery for digital mapping, GIS and geopositioning are, however, yet to be fully established and the models, procedures and computational systems required for higher-accuracy applications require further research. The aim of this project, which is a collaboration with SKM, is to develop the tools necessary to validate Quickbird imagery as a source for geospatial information collection, to develop the associated data processing systems to proof-of-concept stage and to experimentally verify these systems.Read moreRead less
Real-Time Integration of GPS with INS For Precise Long-Baseline Kinematic Positioning. Although Australian researchers have played an important role in the development of carrier phase-based GPS kinematic positioning algorithms and methodologies over the last two decades, investigations concerning high precision multi-sensor integration have been comparatively limited.

Although Australian researchers have played an important role in the development of carrier phase-based GPS kinematic positioning algorithms and methodologies over the last two decades, investigations concerning high precision multi-sensor integration have been comparatively limited. This ARC project would go a significant way towards remedying this situation by building up theoretical and practical expertise in sensor integration techniques at the postdoctoral level. The outcomes of this project will represent a significant contribution to Australian R&D in the fields of precise positioning and navigation, since they will be directly applicable to the design and development of a variety of integrated multi-sensor systems.Read moreRead less

This project will develop the necessary new image processing algorithms, computational models and signalisation strategies to facilitate a significantly higher precision measurement capability for vision metrology (VM) systems incorporating colour digital cameras. VM systems for 3D industrial and engineering measurement currently employ panchromatic digital cameras, because the colour filter arrays used in colour cameras adversely affect image mensuration accuracy. Yet, off-the-shelf colour cameras are ubiquitous and have advantages of ready availability and cheaper cost. This research will overcome the limitations of colour sensors and enable both a broader range of 3D measurement applications and an enhanced commercial potential for VM.Read moreRead less
