Tracking Land Displacement From the Sky

Surveyor-General Victoria (SGV) has successfully completed a transformative high-precision Global Navigation Satellite Systems (GNSS) monitoring survey across Victoria's Otway and Gippsland regions. This NCRIS enabled survey, conducted once every four years, has captured land displacement in new detail. 

Using a network of stable survey marks, SGV collected seven days of continuous GNSS satellite observations to calculate the exact position of each survey mark. 

AuScope was critical to establishing the network of 50 stable survey marks in 2010. In addition, the AuScope-funded AGOS pool of GNSS field equipment enabled the four-yearly repeat observation of the survey marks and analysis of the magnitude and extent of land displacement across the region over time.
