Van Diemen Gulf Bathymetry Survey, 30m Resolution GeoTIFF

A 30-meter resolution bathymetry grid of Van Diemen Gulf, NT, was acquired for the Australian Hydrographic Office between June and October 2021. Guardian Geomatics conducted the survey onboard the MV Offshore Guardian and MV Special Order using a Kongsberg EM2040-07 MKII multibeam sonar. The processed data is exported as a 32-bit floating point GeoTIFF.

Use Cases

• Model seabed topography based on high-resolution bathymetry data.
• Analyze underwater terrain features for marine planning based on the 30m grid.
• Integrate bathymetric data into nautical charting systems based on the survey's stated purpose.
• Study sediment transport and coastal erosion patterns based on detailed depth measurements.

Strengths

• Survey conducted with a Kongsberg EM2040-07 MKII multibeam sonar, a high-precision instrument.
• Data processed and exported as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The dataset is explicitly not to be used for navigational purposes, limiting its primary application.
