Crowdy Head Offshore Seabed Bathymetry and Backscatter, 5m Resolution

Crowdy Head, New South Wales, Australia, was surveyed for seabed mapping between April 20 and 30, 2021. The dataset contains 32-bit floating point GeoTIFF files of bathymetry and backscatter data at a 5-meter resolution, processed from multibeam sonar data. The survey was conducted by the New South Wales Department of Planning and Environment as part of the SeabedNSW program.

Use Cases

• Modeling underwater terrain and slope stability based on high-resolution bathymetry.
• Classifying seabed substrate types based on backscatter intensity data.
• Establishing baseline environmental conditions for marine park management as mentioned in the description.
• Supporting coastal engineering and infrastructure planning with detailed seafloor maps.

Strengths

• Data has a high spatial resolution of 5 meters.
• Survey methodology and standard operating procedures are documented in a publicly available PDF.
• Data collection period is precisely defined as April 20-30, 2021.

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 data is not to be used for navigational purposes.
