List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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. | Prepare for spatial data collection. | 1.1. | Task requirements are reviewed and spatial data collection is planned in consultation with appropriate persons. |
| 1.2. | GNSS equipment is selected and checked according to task requirements. |
| | | |
2. | Use GNSS equipment to collect data. | 2.1. | Site conditions are checked to identify factors that could obstruct or interfere with GNSS operation and impact on accuracy of data. |
| 2.2. | Conditions for obtaining optimum GNSS positions are determined and basic methods to improve accuracy of GNSS point positioning are applied. |
| 2.3. | GNSS equipment is set up and operated according to organisational requirements. |
| 2.4. | Point positional data is collected, validated and recorded according to task specifications and organisational requirements. |
| 2.5. | Checked data is collected according to organisational requirements. |
| | | |
3. | Finalise spatial data collection. | 3.1. | Data is downloaded and verified, and additional data gathered where required according to organisational requirements. |
| 3.2. | Data is processed, and reports and documentation are completed according to organisational requirements. |
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 global navigation satellite systems (GNSS) for two different tasks in consultation with colleagues.
While collecting the above spatial data, the person must:
collect point positional data and attributes to surveying accuracies for the task, both by single point positioning and differential techniques for designated datum and map projection
communicate clearly with others to clarify data collection tasks and report task information
comply with organisational and legislative requirements for identifying hazards and working safely
operate the equipment specified in the assessment conditions, and comply with industry and organisational methods for data collection
plan work tasks to take into account factors that affect accuracy of data collection using GNSS
spatially view collected positional data, and non-spatially view collected attributes
verify accuracy of a sample of collected points by recollecting points or other suitable method.
A person demonstrating competency in this unit must demonstrate knowledge of:
difference in heights and height datums between GNSS heights and heights on Australian Height Datum
factors that affect accuracy of data collection by GNSS
methods for checking accuracy of data collected
purpose of and methods for setting designated datum and map projection
typical accuracies obtainable with different GNSS techniques.
The following must be present and available to learners during assessment activities:
equipment:
GNSS equipment and any associated software
specifications:
job specifications and plans
organisational policies and procedures relating to work health and safety
relationships with team members and supervisor:
working in a team.
Timeframe:
as specified by task and organisational requirements.
Assessor requirements
As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.
