Geoscience Australia Bathymetry Compilations Extent as of June 2019

Geoscience Australia bathymetry compilation products represent the current extent of seafloor depth data as of June 2019. The dataset consists of polygons showing the spatial coverage of each compilation, with attributes detailing data sources, product specifics, and access methods. Contributing individual survey data is referenced in a separate AusSeabed Bathymetry Holdings dataset.

Use Cases

• Map regional seafloor coverage based on polygon extents mentioned in the description
• Assess data source provenance for bathymetric studies based on the attributed source information
• Plan marine survey campaigns by identifying existing data coverage gaps based on the compilation extents

Strengths

• Polygon extents provide clear spatial boundaries for each bathymetry compilation product.
• Attributes contain specific information on data sources, product details, and access methods.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
