Description
This unit specifies the skills and knowledge required to conduct advanced remote sensing analysis on digital imagery. It includes using software and image processing systems to perform the required image enhancements, manipulations and analysis. The unit also includes performing supervised and unsupervised classifications on datasets and conducting related error analysis.This unit is suitable for surveyors and skilled spatial information system (SIS) technicians who use broad theoretical and technical knowledge to analyse information as well as interpret and provide solutions to unpredictable and sometimes complex surveying/spatial information problems. The unit supports those who work in a technical management role in a spatial information services team, in areas such as cartography, town planning and mapping. All work must be carried out to comply with workplace procedures, in accordance with relevant state/territory regulations that govern surveying work, as well as work health and safety (WHS) legislation and regulations that apply to the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
