Abstract: A complete, high-resolution coastline of Antarctica is extracted from an
orthorectified mosaic of Radarsat-1 Synthetic Aperture Radar (SAR) images
acquired in 1997. The absolute accuracy of planimetric position of the
resultant coastline is estimated better than 130 m, and its spatial resolution
(25 m) is adequate for supporting cartographic and scientific applications at
1:50,000 scale. The data set is given as an ArcInfo line coverage in ArcInfo
interchangable format. The coverage is in Polar Stereographic projection with
reference to WGS84 ellipsoid.
