摘要：

Based on the setting up of the function relation between the radiant brightness of ice surface and the elevation control point in Antarctica, the experiments for the extraction of elevation information by using thermal infrared image of Landsat TM band 6, and the ice-surface topographical maps in area nearby Larsemann Hills have been performed.
