Coastal Seabed 3D Models for Keppel Bay and Fitzroy River

Geoscience Australia produced free, Web-viewable 3D models of coastal seabed characteristics. The models integrate spatial data like digital elevation models, multibeam bathymetry, sediment samples, benthic habitats, and satellite imagery for the Keppel Bay and Fitzroy River area in Queensland, Australia. The data is presented using the open-source Virtual Reality Modelling Language (VRML) format.

Use Cases

• Analyze seabed morphology by visualizing integrated digital elevation models and multibeam bathymetry data.
• Correlate sediment sample locations with benthic habitat classifications within the 3D spatial context.
• Overlay satellite imagery on bathymetric models to study coastal water clarity and seabed feature relationships.
• Use the VRML models for stakeholder communication and planning by presenting integrated DEMs, habitats, and bathymetry.

Strengths

• Integrates multiple spatial data types (DEMs, bathymetry, sediment samples, habitats, imagery) into a single model.
• Uses an open-source, ISO-standard file format (VRML) for accessibility.
• Models are designed for Web delivery, facilitating easy sharing with end-users.

Limitations

• Specific row counts, file sizes, and data resolution for individual layers are unknown.
• Geographic scope is limited to the Keppel Bay and Fitzroy River area in Queensland.
• Data freshness is unclear as the model is described in a paper; underlying source data may be older.
