Reconciling Bathymetric Height Datums in Australia: AODN Report

Australian Ocean Data Network published a report on reconciling vertical height datums for bathymetry in Australia. The research focuses on methodologies to calculate uncertainty for short-span Mean Sea Level observations relative to a long-term reference epoch. The report also presents alternative options for high and low water tidal planes with uncertainties to define the intertidal zone.

Use Cases

• Integrating terrestrial and marine height datasets based on the described datum reconciliation methodologies.
• Calculating uncertainty for coastal Mean Sea Level observations based on the presented methodology.
• Defining the intertidal zone in Australia using the presented alternative tidal plane options.
• Joining bathymetry datasets referenced to different datums like Chart Datum and Lowest Astronomical Tide.

Strengths

• Report published by the Australian Ocean Data Network, a recognized organization.
• Focuses on a specific geodetic problem of datum disparity between land and sea data.
• Presents a methodology for uncertainty calculation of Mean Sea Level observations.

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.
• Row count is unknown, which may limit suitability assessment.
