Australian quasigeoid modelling: Review, current status and future plans

Abstract

We review the history of quasi/geoid modelling in Australia, from the first model produced in 1967 to the most recent AGQG2017. b) The results of more than 10,000 trial quasigeoid solutions are presented, computed to assess whether methods used to produce AGQG2017 could be improved. c) Details of a new Australian vertical reference system, and future planned efforts to improve the underlying quasigeoid model are given.
