It has been compiled using 1456 unique data sources from multibeam echosounders, single-beam echosounders, LiDAR, 3D seismic first returns, Electronic Navigation Charts and satellite derived bathymetry alongside higher-resolution regional compilations. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve shallow coastal depth modelling to present a seamless transition between land and sea. All source bathymetry data were extensively edited as 3D point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum. This new continental-scale grid represents decades of data collection, analysis, investment and collaboration from Australia’s seabed mapping community and is a significant improvement on the 2009 and 2023 compilations.The data extends across a vast area from 92°E to 172° E and 8°S to 60° S. This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. Australia's marine jurisdiction offshore from the territory of Heard and McDonald Islands and the Australian Antarctic Territory are not included.Acknowledgements: * CSIRO Marine National Facility (https://ror.org/01mae9353 ) in undertaking this research.

Brief description

The AusBathyTopo 250m (Australia) 2024 Grid is a national-scale depth model for Australia that replaces the AusBathyTopo 250m (Australia) 2023 Grid.

This publication is the result of a collaborative partnership between Geoscience Australia, the Australian Hydrographic Office, James Cook University, and the University of Sydney. It has been compiled using 1456 unique data sources from multibeam echosounders, single-beam echosounders, LiDAR, 3D seismic first returns, Electronic Navigation Charts and satellite derived bathymetry alongside higher-resolution regional compilations. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve shallow coastal depth modelling to present a seamless transition between land and sea. All source bathymetry data were extensively edited as 3D point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum. This new continental-scale grid represents decades of data collection, analysis, investment and collaboration from Australia’s seabed mapping community and is a significant improvement on the 2009 and 2023 compilations.

The data extends across a vast area from 92°E to 172° E and 8°S to 60° S. This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands.

Please see the Datasources_aus240_DEM_V2_public.csv sheet in the downloads section for more information on contributing surveys noting that much of the data for this project came from the AHO and will not be individually identified.

Going forward it is intended that this resource will be updated intermittently when resources allow and as new foundational data becomes available.

Notes

Purpose
This project aimed to develop a new national-scale digital elevation model (DEM) for the Australian region at a grid pixel resolution of 0.0025-arc degree (about 250 m). A national-scale DEM is a critical spatial dataset used to assist policy making, such as informing depth information for wind farm development. In addition, a new grid is required to improve the geomorphic detail about the location and spatial extent of seabed features for the Australian shelf and adjacent continental slopes. The new grid utilised the latest data sourced from ship-based multibeam and singlebeam echo sounder surveys, ENC tile spot depths, airborne LiDAR bathymetry surveys, satellite derived bathymetry data, coastline and near surface feature data.
