Application
This unit of competency specifies the outcomes required to conduct a geodetic survey based on specifications and client requirements. The unit covers project management tasks relating to scheduling, measuring, recording and monitoring work progress and planning for risks and contingencies. The unit also covers applying reference surfaces and projection planes to geodetic components, and performing geodetic calculations. The unit requires using specialist equipment to measure, record and reduce data, including global navigation satellite system (GNSS). The unit requires the ability to perform geodetic calculations, validate the accuracy of data, and identify discrepancies between specifications and actual activities. It also requires using a range of coordinate systems, such as Map Grid of Australia (MGA) and Geocentric Datum of Australia (GDA) to manage surveying data.
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.
