More accurate gravity anomalies from the Australian National Gravity Database

Abstract

Many of the methods commonly used to calculate gravity anomalies have been around since the beginning of gravity surveying when calculations were done by hand and local horizontal and vertical datums were used. These days computing power is not a concern and most surveys are carried out using GPS technology with global datums. Geoscience Australia is reviewing the methods used to calculate gravity anomalies in the Australian National Gravity Database and is proposing changes such as the use of the GRS80 reference ellipsoid for calculating normal gravity and also as the height datum for anomaly calculations.
