CPPSIS4024
Source and assess spatial data


Application

This unit of competency specifies the outcomes required to source spatial data from a range of media and datasets, and assess its availability and suitability for use in meeting client requirements. The unit covers researching and assessing data suppliers and information, such as metadata and attributes, to determine the most suitable sources of available data to meet job specifications. The unit also covers collecting and setting out data using a computer and software suitable for manipulating and presenting spatial data. The unit requires the ability to measure and reduce data and write technical reports.

The unit supports those who work in support positions for surveying and mapping, town planning, cartography and geographic information systems (GIS).

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

complete required documentation, including written assessments as specified in the range of conditions

communicate clearly with others to clarify and discuss work tasks

comply with legal and organisational requirements relating to:

completing records and documentation

copyright and ownership of spatial data

using and storing equipment

working safely

perform spatial data measurements, reduction and manipulation with accuracy

set out spatial data and related attributes, including:

colour

layer

level

line type

line width

text

verify availability of suitable data with suppliers, taking into account copyright and ownership constraints.
