Description
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.
Notes
Elements and Performance Criteria
