Shaded Relief Perspective View of Oahu Southern Shelf

Computer generated image of the seafloor and coastal area of south Oahu showing seafloor relief. The seafloor image is based on georeferenced bathymetric and backscatter multibeam data collected by the USGS in 1998. Vertical resolution of the data is on the order of 50 cm; horizontal resolution is dependent upon water depth and varies from 6 to 16 m. The black region of the insular shelf indicates seafloor areas not imaged in 1998. The land image is derived from a USGS digital elevation model (DEM). The scale across the bottom of the image is appx 10.2 km. The vertical exaggeration is 25x.
