A Microsoft Windows-based package to transform coordinates to the Geocentric Datum of Australia

Abstract

A coordinate transformation software package has been developed, using Microsoft® Visual BASIC^TM, which operates under the Microsoft® Windows^TM environment. It is capable of transforming geographic data from the existing Australian Geodetic Datum to the new Geocentric Datum of Australia as outlined in an earlier paper in Cartography. The software offers the option to transform single coordinates interactively, or to transform a digital file of up to 250 positions in one minute on a 486DX (50MHz) processor. It can also transform coordinates between other geodetic datums, provided that the necessary transformation parameters are available.
