Summary
Airborne laser scanning for advanced environmental monitoring. This proposal seeks to enhance the national capability for airborne remote sensing of key environmental variables through the acquisition of an airborne laser scanner and inertial navigation system. Many environmental science studies, such as hydrology, soil moisture scaling and salinity, can be significantly enhanced by airborne laser scanning, through the creation of high precision, high resolution digital terrain models.

This proposal seeks to enhance the national capability for airborne remote sensing of key environmental variables through the acquisition of an airborne laser scanner and inertial navigation system. Many environmental science studies, such as hydrology, soil moisture scaling and salinity, can be significantly enhanced by airborne laser scanning, through the creation of high precision, high resolution digital terrain models. Airborne laser scanning can also measure three dimensional vegetation canopy structure, a useful indicator of biomass, carbon storage and vegetation health. This infrastructure will provide Australian researchers with a unique arsenal of remote sensing tools for advanced yet affordable environmental research studies.Read moreRead less
Application of Advanced Geomatic Techniques to Heritage Recording of Greek Antiquities. Heritage recording documents archaeological sites for the benefit of future research and also to assess site degradation. This project combines the latest laser scanning technology, available through the ARC-funded LASCAN consortium, with satellite-based and digital photogrammetric survey techniques to develop a unique methodology for precise 3D recording of such sites.

Heritage recording documents archaeological sites for the benefit of future research and also to assess site degradation. This project combines the latest laser scanning technology, available through the ARC-funded LASCAN consortium, with satellite-based and digital photogrammetric survey techniques to develop a unique methodology for precise 3D recording of such sites. Records of archaeological test sites in Greece will contain unprecedented detail, comprising point clouds of greater than five million individual measurements, and spectral information in the infrared and visible wavebands. The large volume of data collected will be managed in a specially designed spatial database, accessible to the general public.Read moreRead less

The project, which falls under the National Research Priority of safeguarding Australia, will be of significant national and community benefit. The research outcomes will advance close-range photogrammetry (CRP) technology, especially in the critical areas of defence and national security. It will lower the cost base of CRP and expand its commercial potential in new application domains, thus promoting business activity in the broader Australian spatial information industry. 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
Skycontrol 2: Long-range positioning of aircraft using multibase GPS and INS. This extends our ARC linkage project (LP0347509) by one year, where we developed and tested a long-range airborne GPS (global positioning system) using a network of ground-based receivers. While the original objectives have been met, and exceeded in some instances, we have now identified the real need to use complementary positional information from INS (inertial navigation systems). As well as reducing the cost of ai ....Skycontrol 2: Long-range positioning of aircraft using multibase GPS and INS.

While the original objectives have been met, and exceeded in some instances, we have now identified the real need to use complementary positional information from INS (inertial navigation systems). As well as reducing the cost of airborne mapping surveys in Australia, our SkyControl2 system will have the added benefit of increased accuracy and reliability.Read moreRead less
Generation of Digital Elevation Models by Fusion of Image and Terrain Laser Scan Data. There are currently two separate approaches to obtaining digital elevation models of the terrain surface by remote sensing, image based methods using aerial or satellite images and scanner techniques by terrain laser scanners. Each method provides elevations with high accuracy, but both require significant input from an operator during processing. It is proposed to take advantage of the synegies of these two ....Generation of Digital Elevation Models by Fusion of Image and Terrain Laser Scan Data. There are currently two separate approaches to obtaining digital elevation models of the terrain surface by remote sensing, image based methods using aerial or satellite images and scanner techniques by terrain laser scanners. Each method provides elevations with high accuracy, but both require significant input from an operator during processing. It is proposed to take advantage of the synegies of these two forms of data by combining the processing into a single solution for elevation determination by data fusion. This approach will improve the quality and efficiency of elevation determination.Read moreRead less

This project will research, develop and test a GPS-network-based system, SkyControl, for the accurate coordination of airborne mapping sensors. A ground network of GPS receivers will be established and the aircraft positioned at long ranges (100 km) using a network solution, as opposed to the single-baseline solutions used at present. The GPS data from the ground network will be transferred to a central location via the Internet and stored in an intelligent database so as to allow efficient data management and processing. This approach will ultimately reduce the cost and increase the reliability of airborne surveys in Australia and overseas.Read moreRead less

Digital Colour Sensing in Vision Metrology. 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.

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
