This paper will compare the use of multibeam datasets to their terrestrial equivalents such as those derived from lidar and laser scanning. Although all three of these systems can produce point clouds based on XYZ data, the reduced density and greater diffusion of points can create challenges when processing bathymetric data, particularly when surveying wrecks at greater depth. This paper will examine strategies for improving data collection through survey methods and discuss the potential of using water column data. We will also look at how these data are processed to visualise wrecks and aid archaeological interpretations. This will include looking at how software packages can be best utilised when visualising wrecks for both single surveys and monitoring programs.
