Seminar Series 2008

You are invited to attend the Department of Geomatics Seminar Series. Seminars provide a forum for academics, research staff, students and visitors to present their research.

Seminars are generally held on Thursdays at 1.15 pm (unless stated otherwise), in Engineering Block C, Theatre C1 (fourth floor) (location for semester 2 2008 will be Engineering A1).

Contact Dr Stephan Winter (winter [at] unimelb.edu.au) for more information on the seminar.

Visualise your message and make it stick
Competition between bits of information is high and from the sea of information generated every moment only a few messages survive and become important in our lives. Visualising your message can help making it stick. This presentation will show some key ingredients to making your message stand out by showing some concrete examples in the hot topic of climate change. Come along and learn how you can apply visualisation to create impact!

Multisensor personal navigator supported by machine learning
The prototype of a personal navigator, which integrates the Global Positioning System (GPS), micro-electro-mechanical inertial measurement unit (MEMS IMU), digital barometer, magnetometer, and human pedometry to support navigation and tracking of military and rescue ground personnel has been developed at The Ohio State University Satellite Positioning and Inertial Navigation (SPIN) Laboratory. This presentation will provide a review of the navigation techniques suitable for personal navigation followed by the design, implementation and performance assessment of the system prototype, with a special emphasis on dead-reckoning (DR) navigation supported by the human locomotion model. A summary of the performance analysis in the mixed indoor-outdoor environments, with the special emphasis on the DR performance is provided. The system’s navigation limitation in DR mode is tested in terms of time and trajectory length to determine the upper limit of indoor operation before the need for system re-calibration.

"Non-convex" hulls: Efficient generation of simple polygons for characterizing the shape of a set of points in the plane
Thursday 1 MayDenis Driscoll Theatrette, Doug McDonell Building Nathan Quadros Department of GeomaticsDelineating the Littoral Zone: Issues and Solutions
(PhD completion)
The vast majority of boundaries within the littoral zone are based on one of the many possible tidal lines. These tidal lines are defined by the line of intersection between a particular tidal datum and the land mass. This research presents the results of case studies involved in the development of the land and water input datasets and the consequent delineation of tidal lines.

Integrating vector datasets of varying quality
(PhD completion)
As the spatial information industry moves from an era of data collection to one of data maintenance, new integration methods to consolidate or to update datasets are required. These must reduce the discrepancies that are becoming increasingly apparent when spatial datasets are overlaid. It is essential that any such methods consider the quality characteristics of, firstly, the data being integrated and, secondly, the resultant data. This research develops techniques that give due consideration to data quality during the integration process. Applicable to any overlaid vector datasets, they enable preservation of spatial integrity constraints and generate updated quality parameters.

An agent-driven virtual environment for the simulation of land-use decision making
(PhD completion)
This research investigates the use of a virtual decision-making environment as a tool for better understanding individual land-use choice behaviour. A series of quantitative and qualitative experiments were conducted to determine the extent to which subjects’ land-use decisions were affected by varying the visual and social context (as represented by a 3D visualisation and agent-based model) provided in the virtual environment. The extent to which people's values were correlated with their land-use choices was also investigated.

Exposing Uncertainty: Communicating fitness for use for spatial data over the Internet
(PhD completion)
After decades of research into spatial data quality, there has been very little empirical research conducted into how consumers really determine whether data is suitable for them.  Theories were drafted in workshops on quality in the early 1980s but since then spatial data has moved from the specialist domain to the everyday Internet user.  This research has investigated consumer perceptions and reasoning, and consequently suggests some concise strategies for communicating quality to consumers that would obtain data through the Internet.

Cadastral Data Modeling - A Tool for E-Land Administration
(PhD completion)
Electronic administration of land is challenged by increasing needs of clients for land information and by creation of new land related commodities and interests. Existing administration systems, including the latest ICT enabled systems, are not sufficiently flexible to accommodate these new interests and commodities. Nor do they respond to the needs of end users. This research will develop a new cadastral data model that incorporates a broader range of interests and commodities and satisfies the emerging demands of users.

Improved Processing Models for Network Kinematic GPS Positioning in Sparse Networks
(PhD completion)
Network Kinematic GPS can realise centimetre level positioning accuracies using regional networks of reference stations (CORS), with typical separations of up to 70km. This spacing is not practically feasible across large regions such as Australia. To overcome this limitation and expand the utility of GPS, this research developed algorithms to accurately determine GPS biases at CORS sites using undifferenced processing techniques. Results indicate that accurate position solutions can be computed at rover sites that are over 100km from CORS sites.
