Visualizing Underwater Environments Using Multifrequency Sonar
September/October 1999 (vol. 19 no. 5)
pp. 61-65
The development1of a high-speed multifrequency continuous scan sonar at Sonar Research and Development has resulted in the acquisition of extremely accurate, high-resolution bathymetric data. This rich underwater data provides new challenges and possibilities within the field of seabed visualization. This article introduces seabed visualization by describing three example case studies, which use the Seabed Visualization System developed at SRD. All three case studies -- harbor wall, shipwreck, and pipeline visualization -- were implemented using real survey data. The high resolution of the data obtained makes slight changes in the seabed topography easily distinguishable. Annual survey inspections enable comparisons between the data sets, making the visualization system an important tool for management and planning.
