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 interpret and analyse science principles for hydrographic surveying.

It includes performing mathematical calculations for a survey, detailing the fundamentals of physics and identifying the impact of geography and geology on the hydrographic survey.

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.
