Orthorectification of IKONOS imagery of eastern Heard Island, acquired 17 and 25 January 2004
These IKONOS images of the east coast of Heard Island were acquired on the 17th and 25th of January 2004. These images have been used in project AAS2939 as the baseline for analysis and change detection of very high resolution satellite imagery of Heard Island. These IKONOS images provide one of the...
