Description
This unit specifies the skills and knowledge required to perform advanced surveying computations to solve a range of surveying and simple engineering-related problems. It includes the application of mathematical concepts, computations and conversions relating to algebra, statistics, geometry and trigonometry. The unit also includes identifying errors and missing elements. It includes developing appropriate a priori and a posteriori uncertainty values to support compliance with surveying industry standards.This unit is suitable for skilled surveying technicians and skilled spatial information system (SIS) technicians who use a broad range of cognitive, technical and communication skills to select and apply methods and technologies to analyse information and provide solutions to sometimes complex surveying/spatial information problems. Surveying and spatial information skills are applied in a range of industry contexts, including town planning, civil construction, mining, engineering, health, agriculture and defence.All work must be carried out to comply with workplace procedures, in accordance with relevant State/territory regulations that govern surveying work, as well as work health and safety (WHS) legislation and regulations that apply to the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Prepare for surveying computations.
  • 1.1 Identify task requirements in consultation with appropriate persons.
  • 1.2 Identify requirements for accuracy and tolerances according to industry-accepted practices.
  • 1.3 Select computational equipment to perform advanced surveying computations according to task and organisational requirements.
2 Solve advanced computation problems.
  • 2.1 Compute the coordinates of a traverse and adjust and compute missing elements and coordinates.
  • 2.2 Reduce traverse information and simplify to requirements for single horizontal and vertical angle.
  • 2.3 Identify and solve problems involving linear figures of parallel, constant or different width according to standards.
  • 2.4 Solve road intersection problems by calculating the bearing and distance from a relevant point with different road widths according to requirements.
  • 2.5 Perform computations to maintain areas of closed figures according to industry-accepted standards.
  • 2.6 Research and use equipment accuracy information in uncertainty calculations.
  • 2.7 Calculate a priori and a posteriori uncertainty values to demonstrate compliance of data with industry-accepted standards.
  • 2.8 Perform computations on all elements of complex circular and reverse curves and solve missing elements by checking for precision and accuracy according to organisational requirements.
3 Finalise computations.
  • 3.1 Apply rigorous checking procedures to identify errors in computational results.
  • 3.2 Adjust checked measurements and computations as required according to industry-accepted standards and task requirements.
  • 3.3 Finalise and record computations using industry-accepted templates and formats according to organisational requirements.
