Ashmore Reef and Cartier Island Marine Parks Satellite-Derived Bathymetry Acquisition (20220016S)

The Ashmore Reef and Cartier Island Marine Parks Bathymetry was derived by EOMAP form multispectral satellite data from WorldView-3 satellite sensor. This was acquired by the Australian Government as part of the Marine Parks Grant - Round 3, in 2022-2023 and undertaken by EOMAP Australia Pty Ltd and EOMAP GmbH & Co.KG. The survey area encompasses the Ashmore Reef and Cartier Island Marine Parks in Western Australia. These critical geospatial data layers provide the essential environmental baseline information for the long-term monitoring and management of these Marine Parks. Mapping the shallow water zone is of importance both from an environmental and socioeconomic perspective. Having access to digital, georeferenced, high-resolution maps of bathymetry and benthic habitats of shallow water areas, is of fundamental use in the areas of navigation, ecological research, environmental modelling, management and conservation, and monitoring the impacts from climate change. Bathymetry data was processed using the physics-based inversion method to derive quantitative information of the shallow water bathymetry using the reflected sunlight energy in different wavelengths of the visible and near infrared region. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.
