Description
This unit of competency specifies the outcomes required to perform basic spatial computations. It requires the accuracy and ability to follow specifications. Functions would be carried out under direct supervision and within organisational guidelines.
Notes
Elements and Performance Criteria
1 Prepare to perform basic traverse computations.
- 1.1 Task objectives are defined.
- 1.2 Pertinent standards are identified, considered and adhered to in line with project specifications.
2 Execute the task.
- 2.1 Computations are performed on angles and bearings.
- 2.2 Conversions between polar and rectangular modes are performed.
- 2.3 Computations are performed on the coordinates of a simple closed traverse.
- 2.4 Organisational documented and undocumented practices are adhered to.
3 Document the task.
- 3.1 Required documentation is completed according to organisational guidelines.
- 3.2 Information acquired and documentation are stored according to organisational guidelines.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the performance criteria is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Objectives may include:
agreed client requirements
written survey data specifications.
Pertinent standards are standards essential to the accuracy of:
basic measurement:
circular geometry
trigonometry
calculation of horizontal and vertical information
recording.
Project specifications refer to:
detailed technical descriptions of the survey data and its requirements.
Traverse refers to:
a method of surveying in which lengths and directions of lines between points on the earth are obtained by or from field measurements and are used in determining positions of the points.
Organisational documented and undocumented practices may include:
appropriate timelines
data processing requirements
final product formats
formal design parameters
teamwork.
Organisational guidelines may include:
company policy relating to surveying operational requirements
legislation relevant to the work or service function
manuals.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for this Training Package.
Overview of assessment
This unit of competency could be assessed on its own or in combination with other units relevant to the job function, for example CPPSIS3015A Collect spatial data.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of:
applying mathematical principles and skills to a range of surveying problems
conducting calculations in a logical and thorough manner
knowledge of basic mathematical concepts and techniques
understanding accurate surveying calculations
using formulas appropriately and obtaining correct results.
Specific resources for assessment
Resource implications for assessment include access to:
assessment instruments, including personal planner and assessment record book
assignment instructions, work plans and schedules, policy documents and duty statements
registered training provider of assessment services
relevant guidelines, regulations and codes of practice
suitable venue and equipment.
Access must be provided to appropriate learning and assessment support when required.
Where applicable, physical resources should include equipment modified for people with disabilities.
Context of assessment
Holistic: based on the performance criteria, evidence guide, range statement, and required skills and knowledge.
Method of assessment
Demonstrated over a period of time and observed by the assessor (or assessment team working together to conduct the assessment).
Demonstrated competency in a range of situations, that may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.
Obtained by observing activities in the field and reviewing induction information. If this is not practicable, observation in realistic simulated environments may be substituted.
Guidance information for assessment
Assessment requires that the clients’ objectives and industry expectations are met. If the clients’ objectives are narrowly defined or not representative of industry needs, it may be necessary to refer to portfolio case studies of a variety of surveying and spatial information services requirements to assess competency.
Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge (in assessment situations where the candidate is offered a preference between oral questioning or written assessment, questions are to be identical).
Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.
All practical demonstration must adhere to the safety and environmental regulations relevant to each State or Territory.
Where assessment is for the purpose of recognition (recognition of current competencies [RCC] or recognition of prior learning [RPL]), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time.
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge.
Assessment processes will be appropriate to the language and literacy levels of the candidate and any cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.
