CARIS Onboard processes sonar and other sensor data in near real-time, applying the same algorithms as CARIS HIPS and SIPS to automatically generate products like DEMs, mosaics, and HIPS projects. It monitors data collection, automatically imports new data, and updates products continuously so processed data is available for quality control while the survey is still underway. The software has three main components - Process Designer to design workflows, Onboard Service to monitor and process data automatically, and Control Centre to manage and monitor processing.
