North Wollongong Seabed Bathymetry and Backscatter Survey, 2017-2022

A bathymetry survey acquired by the NSW Department of Planning and Environment from August 13, 2017, to March 4,我们发现2022. The dataset contains 32-bit floating point geotiff files of bathymetry and backscatter in 5-meter resolution for the area from Bellambi Point to Stanwell Park, derived from processed multibeam sonar data.

Use Cases

• Map spatial distribution of seabed types based on the described purpose of the project.
• Establish baseline environmental conditions for coastal monitoring based on the described baseline dataset.
• Analyze seafloor morphology and texture using the 5m resolution bathymetry and backscatter data.

Strengths

• Data collection spanned nearly five years, from August 2017 to March 2022.
• High-resolution 5-meter grid for both bathymetry and backscatter data.
• Standard operating procedures and a survey report are referenced, suggesting documented methodology.

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.
• The description explicitly states the dataset is not to be used for navigational purposes.
