Description and Outline

This six-day, 36-lecture course is designed to provide a theoretical and practical background in marine swath survey technology and techniques for hydrographic surveys, continental shelf boundary delimitation, offshore engineering, harbour dredging, fisheries habitat, route survey and scientific research, and provides overviews of:
• the technology and problems associated with shallow water multibeam surveys,
• processing and visualization techniques designed to address the complexities of swath mapping,
• constraints on using swath bathymetry to produce highest quality data.
