CPPSIS5064A
Manipulate and analyse GIS data

This unit of competency specifies the outcomes required to manipulate and analyse data in geographic information systems (GIS).

Application

This unit of competency supports the application of planning, organising, and error analysis; designing and interpreting technical documentation; and a practical understanding of technology. The skills and knowledge acquired on completion of this unit would support the needs of employees in surveying and spatial information services (SSIS).


Prerequisites

Nil

1.3

New procedures for manipulating and analysing data are documented clearly, explaining the procedure and rationale for development.

2

Establish models required to provide outcome.

2.1

Applicability of existing tools, models, theories, applications and solutions is reviewed.

2.2

Feasible parameters, equations and assumptions are specified.

2.3

Evidence Required

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 CPPSIS5063A Produce GIS 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:

producing geographic information data systems that meet the integrity of data standards and client needs

interrogating data to ensure reliability

knowledge of data systems and data capture and manipulation techniques.

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, which 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 SIS 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.
