Options and Strategies for Transition to GDA94

Abstract

The adoption of a new geocentric datum in Australia has been recently proposed. In accepting this proposal. options for making the transition to the new datum will need to be carefully considered. Spatial data can take various forms. ranging from survey control networks through to plans. maps and digital geographic information systems. All such spatial data will have to be related to the new datum when and if that datum Is adopted. This paper presents some of the options for transforming spatial data to the new Geocentric Datum of Australia.

A review of non-stationary spatial methods for geodetic least-squares collocation

“…• In the case of coordinate transformations by LSC, the residual is regarded as a distortion that remains after the application of a conformal datum transformation (e.g., Ruffhead, 1987;Collier et al, 1997Collier et al, , 1998You and Hwang, 2006).…”
