Beagle Marine Park in south-eastern Australia contains geospatial seabed morphology and geomorphology data. The dataset was created using a two-step classification system applied to bathymetry digital elevation models, supplemented by backscatter intensity, seabed imagery, sediment samples, and sub-bottom profiles. It is published by the Australian Ocean Data Network.
Use Cases
- Marine habitat mapping based on seabed morphology classifications.
- Environmental impact assessment based on multi-resolution seabed feature layers.
- Geospatial analysis of seabed topography based on polygon extents of highs, lows, and planar areas.
- Marine park management planning based on interpreted geomorphology characterizations.
Strengths
- Data product uses a nationally consistent two-part seabed geomorphology classification system.
- Features are derived from bathymetry DEMs at multiple resolutions, including a 30 m broad-scale layer and 1 m medium/fine-scale layers.
- Interpretations are informed by supplementary datasets including backscatter intensity, seabed imagery, and sediment samples.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last updated date is 2026-05-05.
