The site was at Easting 605090 Northing 6002080 GDA94 Zone 55, located east of Swampy Plains Creek Road at an elevation of 940 m Australian Height Datum
(AHD), situated mid-slope with a westerly aspect, above a gully at the headwaters of Welumba Creek (Tooma River catchment).
On the other hand, global geoid models do not often coincide with the national height datum
. What is more, in many countries quasigeoid models are applied as the reference datum in contrary to the geoid.
and You, Y.: 2013, Transfer of height datum
across seas using GPS leveling, gravimetric geoid and corrections based on a polynomial surface.
This offset could be a consequence of the different datum definitions among the networks (official vertical datum versus the height datum
of the triangulation benchmarks).
Research interests: geoid modelling, height datums
, gravity field, plane coordinate systems.
