Evaluations of the precision of AUSGeoid98 versus AUSGeoid93 using GPS and Australian Height Datum data

Map-based, graphical and statistical evaluations of the AUSGeoid93 and AUSGeoid98 geoid models of Australia are made using a nation-wide set of 1013 GPS-AHD control points. It is shown that AUSGeoid98 is the superior model for the transformation of GPS-derived ellipsoidal heights to the Australian...

description Map-based, graphical and statistical evaluations of the AUSGeoid93 and AUSGeoid98 geoid models of Australia are made using a nation-wide set of 1013 GPS-AHD control points. It is shown that AUSGeoid98 is the superior model for the transformation of GPS-derived ellipsoidal heights to the Australian Height Datum (AHD), especially in mountainous and coastal regions. These results illustrate the benefits of using additional topographic height and satellite altimeter-derived gravity data in computing AUSGeoid98, since these data were not used in the computation of AUSGeoid93.
