Swathe mapping. A technology used for the detailed 3D mapping of the seabed utilizing a vessel-mounted multibeam sonar that transmits a fan, or swathe, of acoustic energy across the ship track; then resolves multiple depth points across the swathe based upon the slant range and elevation angle of reflected echoes from the seafloor. Lidar is a similar technology to multibeam but using airborne laser bathymetry to swathe map shallow clear waters.
