Abstract
As users and managers of spatial information face the adoption of the new Geocentric Datum of Australia (GDA94), the need for a simple, comprehensive and unique transformation process has emerged as an urgent requirement. Such a transformation process must incorporate distortion modelling in order to take full advantage of the new datum, thereby offering the potential to improve the accuracy of existing spatial data. This paper presents the need for distortion modelling and an investigation and evaluation of various options.
