Synopsis

This is a practical oriented subject and the objective of this practical session is to provide hands on experience on hydrographic surveying and data processing. This will cover areas such as Control survey, shore lining, sounding datum, positioning, installation, integration and calibration of echo-sounders, data collection, log keeping, online data filtering, data post processing, sounding reduction, bathymetric plan. This task will run as a continuous four (04) weeks field task collaboratively with National Hydrographic Office – NARA as an outstation field exercise, during last quarter of the semester.

 

Practical Task

Briefing & System installation, System Testing & verification, Test Run & Calibration, Hydrographic surveying, Hydrographic Data Processing, Hydrographic Data Processing and bathymetric chart preparation, Bathymetric Charting, and Report Writing.
