This unit involves the skills and knowledge required to use remote sensing for hydrographic survey.

It includes using light detection and ranging (LiDAR) for data collection and analysis. It also includes analysing collected data and selecting the most appropriate methods to use.

This unit supports the attainment of skills and knowledge required for leaders with responsibility for performing hydrographic surveying and may lead to certification as a hydrographic surveyor.
