Areas of fine-scale Bathymetric and relative acoustic Backscatter data produced using a mounted Geoswath 125KHZ Interferometric sidescan sonar system, by the HABMAP program. Data is collected using a pole mounting and are tide, sound velocity and motion corrected and are accurate to the sub-metre level (DGPS/POSMV). The HABMAP program, which was initiated to provide fine scale benthic habitat information for NSW State Waters, initiated surveys to provide a minimum of 5 x 5m bin scale bathymetric and backscatter layers for use in GIS applications. Mutlibeam data for each of the Survey Coverage Areas is downloadable from the Australian Oceanographic Data Network - https://portal.aodn.org.au/.
