Van Diemen Gulf Bathymetry Survey Grid

Van Diemen Gulf in Australia's Northern Territory contains bathymetry data acquired by Guardian Geomatics for the Australian Hydrographic Office. Survey operations occurred from 26 June to 5 October 2021 using Kongsberg EM2040-07 MKII multibeam sonar. The final product is a 30-meter resolution GeoTIFF grid.

Use Cases

• Analyze seafloor depth variations across the 30-meter resolution GeoTIFF grid for coastal morphology studies.
• Integrate bathymetry grid data with other marine datasets to model sediment transport in Van Diemen Gulf.
• Use the processed sonar data as a baseline for validating autonomous underwater vehicle navigation algorithms.

Strengths

• Data processed using industry-standard CARIS HIPS and SIPS software.
• Survey conducted over a defined 3-month period from June to October 2021.

Limitations

• Dataset explicitly states it is not to be used for navigational purposes, limiting operational applications.
• Specific row count, column details, and sample data are unavailable for assessing volume.
