Van Diemen Gulf Bathymetry Survey: 30m Resolution GeoTIFF

Van Diemen Gulf in Australia's Northern Territory was surveyed for bathymetry data between 26 June 2021 and 5 October 2021. The Australian Hydrographic Office contracted Guardian Geomatics to conduct the survey using Kongsberg EM2040-07 MKII equipment, with data processed in CARIS HIPS and SIPS software. The final product is a 30-meter resolution, 32-bit floating point GeoTIFF grid of the seafloor.

Use Cases

• Modeling seafloor topography based on high-resolution bathymetry data.
• Updating nautical charts for the Van Diemen Gulf region based on recent survey data.
• Analyzing underwater terrain features for marine habitat mapping based on depth information.
• Supporting coastal and marine spatial planning based on detailed depth contours.

Strengths

• Survey conducted with a Kongsberg EM2040-07 MKII multibeam echosounder, a high-precision instrument.
• Data processed using industry-standard CARIS HIPS and SIPS software.
• Final grid has a defined 30-meter spatial resolution and 32-bit floating point precision.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
