Macquarie Island has been severely threatened by invasive species such as rabbits and rodents, which were first introduced by sealers in the 1880s. Because of this impact the eradication of rabbits and rodents has been planned for the near future. In evaluating the progress and success of the eradication program on Macquarie Island, spatial information in the form of a land cover map on Macquarie Island from remote sensing data should be useful due to its inaccessibility. This study therefore proposes a new approach for mapping Macquarie Island’s vegetation communities based on very high resolution QuickBird imagery acquired on 18 March 2007 and object-oriented classification technique. The VHR satellite data has increased in geometric detail and accuracy, but it has some problems in traditional pixel-based classification. With rich spatial and spectral information from the spatial refinement, the internal variation in a class increases. On the other hand, the object-oriented classification first segments ...
