Seafloor or bathymetry can be displayed in multiple resolutions using a 3D visualization tool. Higher resolution seafloor models are created from multi-beam sonar, or LIDAR source data. Together with live data feeds the seafloor is integrated with real-time weather layers. These visualizations are generated and viewed using combinations of public and custom data in real time over the Internet. Application domains include ocean pipeline, cable, marine, harbor, conservation, coastal resource management, and alternative energy.
