CPPSIS4025
Collect spatial data using GNSS

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency specifies the outcomes required to collect spatial data using global navigation satellite system (GNSS) equipment for surveying purposes, using both single point and differential techniques. The unit covers planning work tasks and setting up and operating GNSS equipment to achieve the required accuracy. The unit includes validating data to identify errors.

The unit supports those who work in support positions collecting field surveying data.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

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.

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.

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.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Spatial data must include:

features and their attributes

horizontal position in latitude and longitude, easting and northing

vertical height.

Appropriate persons must include at least one of the following:

experienced colleague

qualified surveyor

supervisor or line manager.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
