The metropolitan multi-beam bathymetry is a representation of the submerged part of the surface of the coastal strip. The seabed is represented with a very dense 3D point cloud with X, Y and Z coordinates. It is measured with a multi-beam echosounder, and provides very detailed data that can represent submerged elements of relatively small dimensions (even less than a meter).
