Modification History

Release 1.

Replaces superseded equivalent CPPSIS6040A Develop 2-D and 3-D terrain visualisations.

This version first released with CPP Property Services Training Package Version 3.

Application

This unit of competency specifies the outcomes required to develop two-dimensional (2-D) and three-dimensional (3-D) visualisations in a geographic information system (GIS) or computer-aided design (CAD) context. It requires the ability to apply wide-ranging specialised technical, creative and conceptual skills and a broad knowledge of spatial datasets. The unit requires the development of technical documentation incorporating mapping and scientific techniques, as well as the ability to communicate graphically. It also requires an understanding of the latest technologies that are available to remotely capture raw elevation data.

The unit supports those who work in a technical management role in a spatial information services team in areas such as cartography, town planning, mapping and GIS.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
