Elements and Performance Criteria

1. Prepare for spatial data collection.
   • Project specifications, information and control marks are reviewed, and surveying tasks planned in consultation with appropriate persons.
   • Terrestrial technologies are selected according to project requirements.
   • Site conditions are checked to identify factors that could impact on operation of terrestrial technologies and accuracy of data.
2. Operate terrestrial technologies.
   • Equipment is set up according to manufacturer specifications.
   • Equipment is operated to collect data and attributes according to job specifications.
   • Identified survey components are measured and data is reduced according to job specifications.
   • Measurements are validated and recorded according to job specifications and data collection plan.
3. Finalise spatial data collection.
   • Data is checked and adjustments are made to identify and correct errors, and where required additional measurements are taken.
   • Data is downloaded and project documentation completed according to organisational requirements.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also collect spatial data using terrestrial technologies for two different projects in consultation with colleagues.

While collecting the above spatial data, the person must:

plan work tasks by checking control marks and ensuring site conditions are appropriate for surveying tasks

use a total station to collect the spatial data and related attributes

measure and calculate basic spatial data based on control marks and set coordinates

communicate clearly with others to clarify and report project information

comply with organisational and legislative requirements for:

identifying hazards and working safely

recording, storing and filing data

comply with manufacturer specifications when using above equipment

use industry-accepted standards and procedures for checking accuracy of spatial data.
