A research report addressing the reconciliation of vertical height datums for bathymetric data in Australia. The project focuses on methodologies for calculating uncertainty for Mean Sea Level observations and presents alternative options for tidal planes. The report was published by the Australian Ocean Data Network and last updated in May 2026.
Use Cases
- Integrating bathymetry datasets referenced to Chart Datum or Lowest Astronomical Tide based on the description of datum disparities.
- Calculating uncertainty for short-span Mean Sea Level observations relative to a long-term reference epoch as described in the methodology.
- Defining the intertidal zone around Mean Sea Level using presented alternative high and low water tidal planes with uncertainties.
Strengths
- Report provides a methodology for calculating uncertainty for Mean Sea Level observations.
- Focuses on reconciling two distinct height datum systems used in Australia: Australian Height Datum and Chart Datum/LAT.
