A GDA94 Transformation Grid for Tasmania

Abstract

As Australia moves towards the adoption of the new Geocentric Datum of Australia (GDA94), each State and Territory will have to implement a process for the transformation of digital spatial data. Using a detailed distortion model, the Tasmanian Office of the Surveyor General has developed a transformation grid that will allow data to be moved from the current to the new datum in a simple, accurate and efficient manner.
