Application
This unit of competency specifies the outcomes required to collect spatial data using terrestrial technologies, including total station. The unit covers planning work tasks to identify control marks, as well as equipment set-up and operation. The unit includes validating data to identify errors, and making corrections and adjustments using industry-accepted methods to achieve required accuracy range.
The unit supports those who work in support positions in a surveying and spatial information services team in areas such as surveying, town planning, cartography, mapping and geographic information systems (GIS).
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. | ||

1.3. | Site conditions are checked to identify factors that could impact on operation of terrestrial technologies and accuracy of data. | ||
2. | Operate terrestrial technologies. | 2.1. | Equipment is set up according to manufacturer specifications. |
2.2. | Equipment is operated to collect data and attributes according to job specifications. | ||
2.3. | Identified survey components are measured and data is reduced according to job specifications. | ||
2.4. | Measurements are validated and recorded according to job specifications and data collection plan. | ||
3. | Finalise spatial data collection. | 3.1. | Data is checked and adjustments are made to identify and correct errors, and where required additional measurements are taken. |
3.2. | Data is downloaded and project documentation completed according to organisational requirements. | ||
Evidence of Performance
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

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.
