Multitemporal satellite images can be used to determine the velocity field, an important parameter in the study of ice streams, by measuring the displacement of features on the moving glacier surface. Bindschalder and Scambos (1991) developed and tested a numerical cross-correlation method for measuring the velocity of crevasses and related features on multitemporal satellite imagery. This paper describes the application of the cross-correlation method to the Scott Coast (Victoria Land, East Antarctica) and in particular to the Drygalski Ice Tongue and David Glacier; Landsat images from 1973 to 2001 were used in this study.
