Terradepth Processes Seafloor Data at the Edge with Cesium ion Self-Hosted

Monica Witzig-Wamsley,
About 25% of the global seafloor has been mapped in high resolution, according to NOAA, leaving a lot of work to be done. It’s not always practical or safe for humans to be involved, and that’s where Terradepth comes in: its autonomous underwater vehicles collect vast amounts of 3D seabed data hosted on Cesium ion Self-Hosted and streamed to its CesiumJS-powered app, Absolute Ocean.
