Geoscience Australia Data produced seabed morphology and geomorphology maps for a subset of Zeehan Marine Park. The data product was derived from a 2-meter resolution bathymetry DEM compiled from a multibeam survey and classified using a nationally consistent scheme. The dataset was last updated on 2026-05 14.
Use Cases
- Classifying seabed geomorphology features based on the described national classification scheme.
- Mapping polygon extents of topographic highs, lows, and planar areas using semi-automated GIS tools.
- Informing marine spatial planning and habitat modeling based on high-resolution bathymetry and interpreted geomorphic characterizations.
- Supplementing bathymetric analysis with backscatter intensity and seabed imagery data mentioned in the description.
Strengths
- Derived from a high-resolution 2-meter bathymetry digital elevation model (DEM).
- Uses a nationally consistent seabed geomorphology classification scheme for mapping.
- Classification informed by supplemental datasets like backscatter intensity and seabed imagery.
Limitations
- Row count is 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.
