Abstract
The main objectives of the 2000 geodetic survey of Heard Island were to upgrade and extend the existing geodetic survey network to give a better coverage of the island and to establish accurate, globally compatible coordinates for all spatial data applications on the Island. In addition, GPS observations would provide information for the long-term measurement of horizontal and vertical movement. In the long term, these fundamental positions will provide information on the contemporary motion of Heard Island for comparison with geological records, with special emphasis on the Australia-Antarctic separation and the mid ocean ridge. In the meantime they provide a consistent and globally compatible spatial framework for all other studies on the Island. This report documents the methods and results of these surveys.
