Version 1.0
Issue Date: April 2024


This unit of competency specifies the outcomes required to perform basic surveying computations in a plane coordinate system. The unit covers computations and conversions based on basic mathematical concepts of algebra, geometry and trigonometry. Computations are done on simple regular geometric figures, traverses, angles, bearings, distances, plane coordinates, heights, perimeter and area.

The unit supports those who work under supervision in a surveying and spatial information services team to perform basic computations associated with field work and data collection.

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

convert between:

polar and rectangular coordinates

vertical angles and gradients and vice versa

check accuracy of above computations.

During the above surveying computational tasks, the person must:

communicate clearly with others to clarify work tasks and computational results

comply with organisational requirements and industry-accepted methods for systematically and legibly laying out computations

use organisational documents to complete required records.

A person demonstrating competency in this unit must demonstrate knowledge of:

common surveying and mathematical terms used in basic surveying computations

industry-accepted methods for performing and laying out different types of basic surveying computations

organisational policies and procedures for completing surveying records and documentation.

The following must be present and available to learners during assessment activities:

equipment:

scientific or programmable calculator or software application

specifications:

task specifications

relationships with team members and supervisor:

working under supervision.

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.

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.

Elements describe the essential outcomes.

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.
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.
