Marine Seabed Habitat Mapping (HABMAP) Extent, New South Wales

The spatial extent of seabed habitat data collected & collated for New South Wales Coastal waters. The HABMAP program has provided fine scale benthic habitat information for NSW State Waters. Targeted areas use surveyed bathymetric and backscatter layers for Habitat classification. Data is collected using a pole mounted Geoswath 125KHZ Interferometric sidescan sonar system. Data are tide, sound velocity and motion corrected and are accurate to the sub-metre level (DGPS). The shape file presented here is a collation of the spatial extent of the area of mapped sea floor habitat data from a variety of sources including; the OEH HABMAP program, digitised from aerial photographs and plotted external high resolution bathymetric data as well as historical habitat data.
