Analysis of multispectral satellite images for ice-streams velocity evaluation

Description
Summary:An important parameter for the study of ice-streams is the evaluation of their velocity field: multi-temporal coverage of satellite images allows surface glacier movements to be measured tracking features on the moving glacier surface. Bindschalder and Scambos (1991) have developed and demonstrated a method of numerical cross-correlation for measuring velocities of crevasses and related features on repeated satellite imagery. In the paper we describe the application of the cross-correlation method in Scott Coast (Victoria Land, West Antarctica) and particular for Drygalski Ice Tongue and David Glacier; Landsat images from 1973 to 2001 have been used in this research.
