Reactions to the new geocentric datum of Australia

Abstract

The practical consequence of Australia adopting a new geodetic (geocentric) datum is that coordinates will change by approximately 200 metres. The implications and impacts of this change win be far reaching and demand the consideration of all those who collect and use spatial data. Recently a national questionnaire was conducted to gauge reactions and assess the issues of most concern in adopting the new datum. This paper summarises the results of this questionnaire.
