Description
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.
Notes
Elements and Performance Criteria
1 Use LiDAR for data collection and analysis
  • 1.1 Collect and analyse data using topographic and bathymetric LiDAR for a hydrographic survey according to workplace procedures
  • 1.2 Analyse the environmental and operational environments in which bathymetric LiDAR surveys are complementary to echo sounder surveys
  • 1.3 Use appropriate hydrographic equipment to gather data for survey
  • 1.4 Extract high and low water lines from LiDAR data sets
  • 1.5 Use computer aided design (CAD) to graphically represent data sets
  • 1.6 Determine the level of turbidity using appropriate equipment
2 Use remotely sensed data
  • 2.1 Calculate data sources in remotely sensed bathymetric data and determine the associated spatial parameters
  • 2.2 Create a shoreline map from images and aerial photographs using geometrical properties
  • 2.3 Analyse the optical characteristics of coastal terrain and floors
  • 2.4 Analyse methods of bottom detection in forming a hydrographic survey
  • 2.5 Analyse remote sensing techniques according to workplace procedures
