<div>The Kimberley Region and WA Reefs Bathymetry was derived by EOMAP form multispectral satellite data from the European Space Agency’s Sentinel-2 satellite sensor. EOMAP was contracted by Geoscience Australia (GA) to provide high-resolution (10m) Satellite-Derived Bathymetry (SDB) for the Priority Australian Seabed Mapping Sites. The survey area encompasses an area within Kimberley Region in Western Australia which includes Ashmore Reef, Browse Island, Cartier Island, Clerke Reef, Cunningham Island, Mermaid Reef, Scott Reef and Seringapatam Reef. 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. A detailed delivery report is provided in: Delivery Report: Satellite-Derived Bathymetry, Priority Australian Seabed Mapping Sites. Reference: 20220304.0888. EOMAP Australia Pty Ltd.
