Understanding your elevation is integral to many decision-making processes; from determining a safe development threshold to avoid flood risk, for monitoring sea-levels, through to making sure sewers flow downhill as designed. But have you ever wondered how a vertical datum is defined and how you then establish this for a country that is also a continent?
This talk explores the history of the Australian Height Datum, the huge task of realising the concept, and how it has been modernised more recently to remain fit for purpose in a modern world where understanding your 3D position is becoming more important than ever.
