Collaborative planning support tools for optimising farming systems (CPSTOF). What you know about what you can grow is becoming a key issue in farm management. Better guidance on alternative land cropping systems that can be grown to optimise farm productivity is needed. Micro-level land classes maps have been identified hby AgWA, farmers and regional development and community groups as an urgent need to enable them to design resilient and diversified farming systems.

Better guidance on alternative land cropping systems that can be grown to optimise farm productivity is needed. Micro-level land classes maps have been identified hby AgWA, farmers and regional development and community groups as an urgent need to enable them to design resilient and diversified farming systems. To this end, we propose integrating high resolution digital multispectral images, GIS and multi-criteria decision analysis techniques to help farmers use input appropriate to the productive capacity of their paddocks and to elaborate sound farm planning based on the potential of the land for specific land uses.Read moreRead less
Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrat ....Geodetic and hydrogeological investigations of groundwater abstraction from confined aquifers: elastic response, heights, and sea level change. Parts of Perth are subsiding by as much as 5 millimetres (mm) per year, thus accelerating sea level rise relative to the land from 3 mm per year to 8 mm per year. The subsidence is most likely due to increased groundwater abstraction. This project aims to extend subsidence mapping in time and space using satellite-borne synthetic aperture radar, calibrated by complementary geodetic techniques, and coupled with new hydrogeological inputs from the Western Australian Department of Water. The research aims to provide science-based information to planners and managers on coastal vulnerability and determine the land response to groundwater abstraction. This will also allow for the correction of sea level change measurements from tide gauges.Read moreRead less
Improved tools for comprehensive monitoring of water-clarity and light availability in coral reef ecosystems. The Great Barrier Reef is a World Heritage Area, home to over 1 million species and provides Australia with $6 billion in annual revenue. The capacity to monitor Australia’s natural resources and changes in condition are integral components of a sustainably and adaptively managed resource. By providing key synoptic tools to comprehensively monitor water quality and ecosystem status, the ....Improved tools for comprehensive monitoring of water-clarity and light availability in coral reef ecosystems. The Great Barrier Reef is a World Heritage Area, home to over 1 million species and provides Australia with $6 billion in annual revenue. The capacity to monitor Australia’s natural resources and changes in condition are integral components of a sustainably and adaptively managed resource. By providing key synoptic tools to comprehensively monitor water quality and ecosystem status, the project will contribute directly to an Environmentally Sustainable Australia and improve national capacity for responding to climate change and variability in coral reef environments. It will enable Australian remote sensing scientists to contribute knowledge and tools to the international community for application to coral reef and coastal waters globally. 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. 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 airborne mapping surveys in Australia, our SkyControl2 system will have the added benefit of increased accuracy and reliability.Read moreRead less
A system for long-range positioning of airborne mapping sensors using a multi-receiver, Internet-compatible GPS network. 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 wil ....A system for long-range positioning of airborne mapping sensors using a multi-receiver, Internet-compatible GPS network. 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
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
Geodetic determination of the amount and spatial-scale of land subsidence and/or uplift in Australia. Heights can change with time, although most users assume that they are static quantities. Geodetic techniques will be employed to produce a vertical velocity model to make time-varying heights consistent and also to correct sea level change estimates at tide-gauges installed on land, that is either sinking or rising.
