Howard Channel Bathymetry Survey, 30m Resolution GeoTIFF

EGS Australia acquired bathymetry data for the Australian Hydrographic Office between 9 Aug 2023 and 13 Sep 2023. The survey covers an area in Howard Channel using a Kongsberg EM2040C sonar system. Processed data is available as a 32-bit floating point GeoTIFF grid with a 30-meter resolution.

Use Cases

• Modeling seafloor topography based on the 30m resolution bathymetry grid.
• Analyzing underwater channel morphology based on the processed survey data.
• Supporting marine spatial planning based on the detailed depth information.
• Calibrating or validating hydrodynamic models based on the precise bathymetric measurements.

Strengths

• Data was acquired using a Kongsberg EM2040C, a modern multibeam echosounder.
• The final product is a 30-meter resolution grid, providing a specific level of detail.
• Processing used industry-standard software CARIS HIPS and SIPS and QIMERA.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
