Orthorectification of IKONOS imagery of eastern Heard Island, acquired 17 and 25 January 2004
Listed in NASA Earthdata CMR
These IKONOS images of the east coast of Heard Island were acquired on the 17th and 25th of January 2004.
Description
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 first high-resolution satellite images of Heard Island and the acquisition dates coincides with the 2004 ANARE expedition.
Several attempts have been made to accurately orthorectify these images. The current images are the most recent attempt based on: a) Co-registration to accurately orthorectified WorldView-2 imagery acquired on 23 Dec 2010 b) Use of a recent and detailed digital elevation model (DEM) acquired by TerraSAR-X for orthorectification. The digital elevation model used in the orthrectification is described by the metadata record 'A Digital Elevation Model of Heard Island derived from TerraSAR satellite imagery'.

Entry ID: heard_dem_terrasar A detailed processing report is provided in the attached document (available for download at the provided URL). The two images (17 and 25 Jan 2004) were mosaicked and used as a single image. The third image of the spit was left out of the processing given the size increase of the image and the limited land area.
The content of the directories is as follows: IKONOS_JAN2004_multi: 4m resolution multispectral bands co-registered to the orthorectified WorldView-2 image (23 DEC 2010) using matching ground control points and a triangulation transformation. IKONOS_JAN2004_pan: 1m panchromatic image co-registered to the WorldView-2 image (23 DEC 2010) IKONOS_JAN2004_pan_sharpened: orthorectified and co-registered panchromatic and multispectral image mosaics in the above directories were used for pansharpening using the Gramm Schmidt fusion algorithm, resulting in a 1m resolution multispectral image.
This metadata record supersedes SIC_266_267_georectification, which describes an earlier orthorectification of the same imagery.
