Multibeam sonars are widely used in applications like high resolution bathymetry measurements, underwater object detection and imaging, etc. Also, they are the promising tool in seafloor characterisation and classification, having several advantages over conventional single beam echosounders. The proposed approach to seafloor classification relies on the combined use of three different techniques. In each of them, a set of descriptors foreseen to be applied in seabed classification procedure, is calculated using a given type of data obtained from multibeam sonar system: 1) the grey-level sonar images of seabed, 2) the 3D model of the seabed surface which consist of bathymetric (x, y, z) points, 3) the set of time domain echo envelopes received in the consecutive beams. In addition, the open source World Wind Java SDK tool for 3D and 4D implementation of imaging and mapping of seafloor multibeam data was presented.
