Geoscience Australia Bathymetry Compilations Extent and Sources as of 2019

Geoscience Australia's bathymetry compilations integrate multiple data sources including survey data and lidar. Each polygon in this dataset defines the spatial extent of a compilation product, with attributes detailing data sources and access methods. The dataset represents the compilation status as of June 2019.

Use Cases

• Identify available bathymetric data coverage for a specific marine region based on the polygon extents.
• Plan new surveys by analyzing gaps in existing data compilations mentioned in the description.
• Trace the provenance of bathymetric models using the attributed information regarding data sources.
• Facilitate data discovery and access by using the documented product details and access methods.

Strengths

• Compilation integrates numerous data sources including survey data and lidar.
• Attributes contain specific information on data sources, product details, and access methods.
• Dataset provides a clear snapshot of available products as of a specific date (June 2019).

Limitations
