This data was gathered in shallow water in and around Bristol docks, UK and processed with GeoSwath, an echosounder by Kongsberg Maritime.

Capturing More with Shallow-water Multibeam

Interferometric sonars are providing a new tool for the hydrographic surveyor in shallow to medium-depth water applications. As we begin to return to normalcy after the deepest recession of most of our lifetimes, many ports, coastal authorities, and inland waterways are starting to look at infrastructure projects that have been kept on hold, and they...
