Staff from the National Snow and Ice Data Center (NSIDC) and the University of New Hampshire have assembled a digital image map and a snow-grain-size image of the Antarctic continent and surrounding islands. This map, a mosaic of Moderate Resolution Imaging Spectroradiometer (MODIS) imagery from the Terra and Aqua satellites, provides a cloud-free view of the ice sheet, ice shelves, and land surfaces at a grid scale of 125 meters and an estimated resolution of 150 meters. All land areas south of 60 degrees south latitude that are larger than a few hundred meters are included in the mosaic. Also included are several persistent fast ice areas and grounded icebergs. The imagery is available at an FTP site linked from the project summary page.
