The Australian Geological Survey Organistaion, in co-operation with Desmond Fitzgerald and Associates and the Australian Hydrographic Service, has produced a set of digital bathymetry, gravity and magnetic grids for Australia's margin, with resolutions of 250-1000m. They represent a major upgrade of marine ship-track potential field and bathymetry data in Australian waters for the purpose of developing fundamental products for geological interpretation. In integrating data from many sources, levelling techniques have been developed to correct crossover and other errors, and the ship-track data have been merged with satellite and high-resolution onshore sources.
