Level 4, Room CE415
Professor of Geodesy and Navigation in the School of Civil and Environmental Engineering
Level 1: Investigate how geospatial technology such as GPS and digital mapping is used for science, and by society in general.
Level 2: Investigate the technology and applications of satellite-, wireless- and inertial-based sensors for high accuracy positioning.
Level 3: Interested in positioning technologies, especially GNSS, and their applications across the whole spectrum of uses from Navigation to Geodesy.
Interest in engineering
Why did you get into engineering?
My fascination in old maps and the role of explorers in opening up Australia led me to Surveying, however my research interest in the geosciences, mathematics and satellite technology drew me to Geodesy.
What are your research goals?
To “spatially enable” all aspects of life, through the further development of technologies and systems that provide continuous, seamless, high accuracy positioning of objects, people and every feature on the surface of the Earth.
What do people not understand about what you do?
The challenge for my whole adult life has been that people do not understand the rich and myriad ways in which Surveying and Geospatial Engineering affects our daily lives, underpins the wealth of our nation, or helps us better understand our dynamic Earth.
Advice for prospective Surveying and Geospatial engineers
Surveying is a profession that provides engineering services for a wide range of human activities, utilising an amazing array of hi-tech geospatial technologies for mapping, measuring, navigation and environmental monitoring. Many opportunities in traditional Surveying, as well as the new geospatial information disciplines.
