Session 2 Class & Order Uncertainty • Based on equipment & technique • Based on uncertainty of each measurement, control • Empirically derived coordinates • Assigned (with help of Least • Statistically derived (Least Squares) Squares) • Useful when classifying new • Useful when adjusting all survey network to existing measurements simultaneously network In 2014, ICSM SP1 (Standard for the Australian Survey Control Network) transitioned to uncertainty as the basis for evaluating and expressing the quality of measurements and positions. 8

Session 2 SMES, SCN and Uncertainty – Horizontal Coordinates National Adjustment Statistics ~500,000 Stations • SCN(GDA) – Coordinates derived from National ~1.9 million Measurements Adjustment in GDA2020 • Horizontal (Positional) Uncertainty derived from Victorian Component of National Adjustment National Adjustment ~44,000 Stations ~280,000 Measurements 9

Session 2 SMES, SCN and Uncertainty – Vertical Coordinates Victorian Levelling Network Adjustment ~300 Constraining • SCN(AHD) – Height derived from Victorian Levelling Stations ~25,000 Stations Network (part of Australian National Levelling Network) ~31,000 Measurements • Vertical (Positional) Uncertainty mostly derived from Victorian Levelling Network Adjustment 10
