Multibeam Sonar Characterisation of Seafloor in the Context of Visualisation and Dissemination of Marine Data
Abstract
The paper presents the seafloor characterisation method based on multibeam sonar data. it relies on using three types of multibeam seafloor sensing data: 1) the grey-level sonar images (echograms) of seabed, 2) the 3D model of the seabed surface which consists of high resolution bathymetric data, 3) the set of time domain bottom echo envelopes received in the consecutive sonar beams. The classification is performed by utilisation of several statistical methods applied to analysis of a set of seafloor descriptors derived from multibeam data. In the second part of the paper, the use of a real-time, remotely accessible GIS for implementation of imaging, spatial analysis and mapping (including the 3D model) of seafloor and other marine data is presented. The marine GIS is capable of integrating the data from various sources related to off-shore as well as coastal area and has been developed to deliver multi-resolution maps designed for different scale observations of marine environment and various ecosystem components.
