Unit of competency

Modification History

Release 1.

Replaces superseded equivalent CPPSIS5054A Perform geodetic surveying computations.

This version first released with CPP Property Services Training Package Version 3.

Application

This unit of competency specifies the outcomes required to perform geodetic surveying computations to solve a range of geodetic surveying problems. The unit covers applying mathematical concepts and formulas to geodetic components and performing computations relating to reference surfaces and projection planes. It covers using techniques for data reduction and checking data. It requires the ability to analyse data to comply with standards, and to consult with others to clarify and report on work tasks.

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.
