Glacier velocity in the Everest region


This velocity map was created by co-registering two ASTER images to sub-pixel accuracy and then feature tracking on them using Cosi-Corr. The debris-covered surface allows the feature tracking algorithm to correlate surface displacement effectively, however, matches are sparser in the clean-ice areas (e.g. the Khumbu Icefall) where glacier velocity is high but there are fewer surface features.
