Geographe Marine Park Bathymetry Grid at 5-Meter Resolution

A 5-meter resolution bathymetric grid of the Geographe Marine Park, part of Australia's network of 58 marine parks covering 3.3 million square kilometers. The data was compiled and processed by Geoscience Australia from its bathymetry holdings, supporting marine park management plans effective from July 2018. The release includes a panchromatic geotiff image combining bathymetry with hillshade and derived morphological surface classifications.

Use Cases

• Modeling seafloor geomorphology based on the described morphological surface categories (Plain, Slope, Escarpment).
• Creating habitat maps for marine park management using the high-resolution bathymetric grid.
• Integrating bathymetry with ecological data for 'eco-narrative' documents mentioned in the description.
• Analyzing slope characteristics for geological studies using the two-part seafloor classification scheme.

Strengths

• High 5-meter spatial resolution for detailed seafloor analysis.
• Data is integrated with a hillshade image to enhance geomorphological interpretation.
• Supports a national network of 58 marine parks covering 40% of Australia's exclusive economic zone.
• Based on a documented, semi-hierarchical seafloor classification scheme (Dove et al., 2016).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
