Release 1. This is the first release of this unit of competency in the NWP National Water Training Package.

This unit involves the skills and knowledge required to manage hydrographic surveying projects.

It includes planning hydrographic survey projects, producing reports and other products whilst applying relevant professional ethics, industry standards, and national and international legislation and conventions.

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.
