Application
This unit of competency specifies the outcomes required to perform basic surveying computations in a plane coordinate system. The unit covers computations and conversions based on basic mathematical concepts of algebra, geometry and trigonometry. Computations are done on simple regular geometric figures, traverses, angles, bearings, distances, plane coordinates, heights, perimeter and area.
The unit supports those who work under supervision in a surveying and spatial information services team to perform basic computations associated with field work and data collection.
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
