CO-L-MAR - Singlebeam and Multibeam Echosounder

Bathymetric surveys are carried out every time is requested to know in details the seafloor morphological conformation. The bathymetry would be performed by mean of singlebeam or multibeam echosounder. The parameter to evaluate the quality of bathymetric survey is the reliability and accuracy obtained (up to 5x5cm by mean multibeam). On the survey vessel the echo sounder data and the GPS positioning information are recorded and displayed by the navigation system. Afterwards the data are processed with tide level correction and coordinates conversion. Finally, the data can be displayed with different formats: elevation maps, contour lines maps, profiles, 3D images (above 3d sections in a pipelines shore approach) and volumes computation.
