Digital elevation model bathymetry mapping of seafloor using qinsy qloud

Abstract

Digital elevation model of seafloor mapping is one of the most active modern underwater acoustics domains to produce near real visualization of the underwater terrain, attracting the attention and knowledge exploration in many branches of science and technology. This study takes interests on the three dimensional (3D) geometrical description of the seafloor topography as well as to have idea on dynamic behavior of seabed morphology and its material properties. The aims of this study are to generate 3D digital elevation model of the seafloor, visualize and interpret the 3D model and analyze the effect of data duplication on depths where the main source of the data is multibeam echo sounder. The multibeam bathymetry technique has an unlimited range of application in the marine data acquisition and underwater investigation. The recent technological advancement and development on the multibeam bathymetry technique has led to the improvement of underwater mapping and study of seafloor classification. This Project described step by step approach and methodology adopted which focusing on the application of high resolution multibeam, RESON SeaBat8124. When the 3D bathymetric model produced is compared to Surfer and ArcMap software, the 3D model show the same topographical shape and the 3D model look similar. The shape produced by QINSy QLOUD is also the same.
