Application
This unit of competency specifies the outcomes required to perform advanced surveying computations to solve from a range of surveying and basic engineering-related problems. The unit covers applying mathematical concepts, computations and conversions relating to algebra, statistics, geometry and trigonometry. It also covers solving a range of surveying problems to identify errors and missing elements, and make necessary adjustments to computations. It requires the ability to analyse and evaluate spatial data as the basis for performing computations.
The unit supports those who work under limited supervision in a surveying team.
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
