The Almeida Carvalho shipwreck was a former hydrographic vessel, which is now used as a dive site. It is used here as a test site to show the advantages of having water column data (light color) for complete wreck detection. The masts, cranes, funnel, guard rails and other details are detected using water column data. CARIS HIPS was used to process and generate the image.
