| SATELLITE IMAGEMAP OF ANTARCTICA at 250 metres |
| |
|
Our Satellite Imagemap of Antarctica uses data from four satellite systems to give a unique combination of realism, clarity and drama. The natural colour of ice and bare rock surfaces comes from a mosaic of Landsat images, with a subtle colour boost from false-colour AVHRR imagery. MODIS imagery is used for pin-sharp detail at the full resolution of 250 metres, with a high-contrast stretch bringing out subtle details across the vast interior ice sheets. Finally, CZCS imagery from our standard Satellite Imagemap of the World provides ocean colour based on chlorophyll concentration. Based on datasets assembled for International Polar Year (2007-2008), this imagemap offers the most up-to-date snapshot of Antarctica's dynamic coastline.
