The Standard for the Australian Survey Control Network – Special Publication 1 (the Standard) and associated Guidelines provide an outcomes based framework that supports the highest level of rigour and integrity in the delivery and maintenance of Australia’s survey control mark network. Version 2 of the Standard completes the transition from CLASS and ORDER to uncertainty as the basis for evaluating and expressing the quality of measurements and positions. The Standard’s definition of uncertainty is intended to be consistent with the ISO definition. The use of the term Local Uncertainty as defined in SP1 version 1.7 has been discontinued in this Standard.
