Australian bathymetry and topography grid

Abstract

This 2 CD package contains the January 2002 edition of the Australian bathymetry and topography grid at 0.01 deg (~1 km) cell size. Both binary and ASCII formats are included, suitable for most common image processing and GIS applications. The topography is from Geoscience Australia's (formerly AUSLIG's) 2nd edition digital elevation model for Australia. It is included for continuity with bathymetric features. The bathymetry is from digitised charts obtained from the Australian Hydrographic Service, swath bathymetry surveys, and other ship-track data of various vintages and navigational accuracy sourced from Geoscience Australia databases. The ship-track data have been levelled to reduce the artefacts due to misties at intersections.

Lineage

The topography is from Geoscience Australia's (GA, formerly AUSLIG's) 2nd edition digital elevation model for Australia. The bathymetry is from digitised charts obtained from the Australian Hydrographic Service, Royal Australian Navy (AHS), swath bathymetry surveys, and other ship-track data of various vintages and navigational accuracy sourced from Geoscience Australia databases. The ship-track data have been levelled to reduce the artefacts due to misties at intersections. The grid was generated from over 200 million data points gathered from numerous data sources as part of the Continental Margins Program. It includes data collected since 1963 from surveys by GA, AHS, industry and foreign agencies, and from over 200 days of modern deep-water seafloor swath-mapping surveys. In some areas not covered by marine surveys, it incorporates bathymetry data derived from predicted bathymetry from satellite measurements.
