Brief description

Data products from multi-beam bathymetry surveys carried out by the New South Wales Office of Environment and Heritage (OEH). Surveys were conducted in and around NSW Coastal and State Waters, using a mounted GeoAcoustics Geoswath 125KHZ Interferometric sidescan sonar system, by the HABMAP program. 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. Products include fine-scale bathymetric and relative acoustic backscatter data in several formats. For each survey there is also a "scientific rigour" document describing the origin and processing of the data, and files showing the geographic coverage of the survey (ESRI shapefile and Google KMZ formats).
