All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).
Orthorectified pan sharpened multi spectral Image of eastern Heard Island from capsize beach to Compton Lagoon. This image was derived from Quickbird satellite imagery captured on 17 January 2003.
More information about the images used, the processing, and the feature mapping are documented in an image report available for download at the url given below.
The image processing was undertaken using the ERDAS Imagine software.
See the metadata record 'Georeferenced Quickbird Multi Spectral Image of Eastern Heard Island from Capsize Beach to Compton Lagoon' (ID - QUICKBIRD_CAPSIZE_COMPTON_GMS) for full image details.
This image was rectified using a combination of control points collected with a hand held GPS unit and surveyed using differential GPS. This image was then orthorectified using the DEM supplied by RADARSAT in July 2003.
The RMS error achieved had a Delta X of 4.86m and Delta Y of 4.62m.
The accuracy achieved was +/- 7.5m.
The Multispectral image has a pixel resolution of +/-3.29m, while the pan image has a resolution of +/-0.6m.
These images were combined to produce a higher resolution colour image known as a pan sharpened image. To produce the pan sharpened image the following parameters were used:
Method - Brovey Transform, Resampling Technique - Cubic Convolution,
Data Type - Unsigned 16 bit.
The pixel resolution of the mosaiced image is 0.6m.
The image was projected to UTM Zone 43 (WGS84).
