Graduate student wins SSSI WA Undergraduate Student Award

Todd Lyon

Well done to graduated surveying student, Todd Lyon, on wining this year’s SSSI WA’s Undergraduate Student Award at the WA Spatial Excellence Awards (WASEA).

Todd won the award based on the quality of his final year project which involved establishing a ‘gravity base station’ at Curtin University.  The project was supervised by Associate Professor Jon Kirby.

Gravity base stations provide an accurate and precise value of the Earth’s acceleration due to gravity at their location, and are used to tie relative gravity measurements from local surveys to the national gravity datum, the Australian Absolute Gravity Datum 2007 (AAGD07).

Todd’s project required learning the fundamentals of gravity surveying (greatly helped by Richard Haines of Haines Surveys), conducting the survey by tying the new Curtin station to several existing AAGD07 stations around Perth using Spatial Sciences’ Scintrex gravimeter, and processing the data.

The results of his work were deemed to be rigorous enough by Geoscience Australia for his new station to be included as a part of the Australian Fundamental Gravity Network (AFGN).

Congratulations to Todd for this well-earned award.
