Rottnest Island Bathymetry Survey for Sonar Calibration

Rottnest Island, Western Australia, is the location for this bathymetric reference surface. The dataset was created from a survey conducted on 11 December 2022 for the Australian Hydrographic Office, using a Kongsberg EM2040P multibeam echosounder. It provides separate 0.5m and 2m resolution grids in three vertical datums (MSL, LAT, Ellipsoid) for calibrating sonar systems.

Use Cases

• Calibrating multibeam echosounder systems based on high-resolution reference bathymetry.
• Analyzing seabed topography near Rottnest Island based on 0.5m and 2m resolution grids.
• Comparing vertical elevation models based on the three provided datums (MSL, LAT, Ellipsoid).

Strengths

• Survey conducted with a specific instrument (Kongsberg EM2040P) on a known date (11 December 2022).
• Provides high-resolution (0.5m) and standard-resolution (2m) grids for two surveyed sites.
• Data processed using a professional hydrographic software suite (Caris HIPS & SIPS).

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.
