Visually interpret image data

Assessment tool

Version 1.0
Issue Date: March 2024


This unit of competency specifies the outcomes required to visually interpret image data to identify the basic features of the landscape, including land cover such as vegetation, roads, railways, buildings, water bodies and terrain forms. Image data can include aerial and terrestrial photographs and satellite images. The images can be digital or in hard copy. Mapping or other appropriate software can be used to assist visual interpretation if it is available. The unit requires the ability to apply the principles and methods of visual image interpretation. This unit is restricted to visual interpretation, as digital enhancement of images is covered in CPPSIS4026 Digitally enhance and process image data.

The unit supports those who work under direct supervision in a surveying and spatial information services team, in positions that support mapping, geographic information systems (GIS) and town planning.

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)
