Lead researchers: Dr Christine Stone and Dr Jim O'Hehir

This project is comprised of several sub-projects which are actively involved in developing solutions for applications using a range or sensors and platforms in different situations across Australia. The project is benefitting from a high level of collaboration between industry and researchers to make multiple data sets available with knowledge sharing on solutions. 

To ensure effective communication with stakeholders, 14 seminars have been delivered across of a range of topics directly and indirectly covered by the project. 

Sub project: Growth and Yield Modelling for the Future (UniSA) 

This sub project has incorporated ground truth data into plot imputation models and shown potential to increase the efficiency, and lower the costs, of ALS surveys by reusing calibration plot data both spatially and temporally. Of importance to the industry is that preliminary results of imputation domain studies have indicated there is potential to increase the imputation accuracy and efficiency, and lower the costs, of ALS surveys by reusing calibration plot data both spatially and temporally.

Sub-project: Ultra high-resolution imaging from Unmanned Aerial Systems (UAS) for detection of weeds and tree health assessment (UTas) 

Data has been collected at three pine plantation sites in Northern Tasmania using a range of sensors: hyperspectral; multispectral, visible and thermal, with the aim of testing which sensors are best at detecting weeds. Data processing is now complete.

Subproject: The automation of forest inventory (University of Sydney)

The sub project is complete and has developed workflows and algorithms for tree-level census using point clouds, deep learning and human-machine interaction. The research indicates tree detection methods developed for high resolution Airborne Laser Scanning (ALS) data based on deep learning object detection have been applied effectively to low resolution ALS data. The implication for forest companies is that using this method, cheaper data can be used to obtain more tree attribute information. A report and software have been provided and the results have been communicated in a seminar.

Results from all three of the above sub-projects have been communicated via individual seminars.
