Unit of Competency CPPSIS4026 - Digitally enhance and process image data
Description
Employability Skills
Learning Outcomes and Application This unit of competency specifies the outcomes required to enhance and process image data using digital techniques. The unit covers using remote sensing software to manipulate, enhance, classify and process data to reveal geographic patterns and relationships and improve resolution. Image data can be digital, multispectral scanner, or radar. Platforms can be aircraft, unmanned aerial vehicles or satellites at low to high altitudes. The unit requires assessing the survey area and project specifications to determine the types and possible sources of image data to meet requirements. The unit supports those who work in a spatial information services team in support positions, such as image analyst, geographic information system (GIS) analyst, GIS officer, or cartographer.No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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

equipment:

computer and software with image enhancement functionality

specifications:

task specifications

organisational policies and procedures relating to:

work health and safety

data privacy and information copyright

physical conditions:

access to equipped workstation

relationships with team members and supervisor:

working in a team.

Timeframe:

as specified by project 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.

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 use remote sensing applications to digitally enhance, process and classify two of the following types of image data for two different projects:

digital aerial photographs

digital terrestrial images

images from an unmanned aerial vehicle

light detection and ranging (LiDAR)

satellite images.

One of the above projects must have a built environment focus, and the other a natural environment focus.

While digitally enhancing and processing the above image data, the person must:

analyse project specifications to clarify types of image data required and to identify possible sources of suitable image data

apply ground controls to aerial photographs

calculate information in digital and hard copy image data to measure and identify scale

communicate clearly with others to clarify and discuss work tasks

comply with industry-accepted standards for processing remotely sensed data

comply with legislative and organisational requirements relating to data privacy and information copyright

comply with organisational requirements relating to health and safety when using screen-based equipment, and completing records and documentation

georeference images

identify and resolve constraints and problems relating to image data

identify ground controls, including targets for horizontal and vertical control

use software applications to access, analyse and enhance image data.

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

basic properties and characteristics of image data used in spatial applications

key features of spectral signatures, discriminant functions, supervised and unsupervised clustering, and ground trothing

organisational policies and guidelines relating to equipment use, health and safety, and accessing and formatting image data and copyright

photogrammetric control requirements relating to three-dimensional (3-D) model image data

possible sources of image data

set-out and format requirements for image data

techniques for enhancing image resolution, including basic interpolation.
