Solitary Islands Marine Park Seabed Bathymetry and Backscatter at 5m Resolution

Solitary Islands Marine Park seabed data was acquired by the New South Wales government from August 2022 to July 2023. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5-meter resolution, processed using Hypack, R2Sonic GUI, and Qimera software. It was created to provide a baseline dataset and map the spatial distribution of seabed types.

Use Cases

• Modeling seabed topography and slope based on the 5m resolution bathymetry data.
• Classifying seabed types and substrates based on the backscatter intensity data.
• Establishing baseline conditions for marine park monitoring based on the stated project purpose.
• Integrating seabed data with other marine spatial datasets for coastal management.

Strengths

• Data has a high spatial resolution of 5 meters.
• Survey was conducted over a defined period from 31 Aug 2022 to 31 Jul 2023.
• Processing methodology is documented in a referenced standard operating procedure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
