Abstract
We present a new method for extracting the direction of surface flow for ice sheets, based on
the detection of flow-induced features that are visible in satellite imagery. The orientation of linear
features is determined using a Radon transform and only requires a single image. The technique is
demonstrated by applying it to the RADARSAT mosaic of Antarctica, over the Lambert Glacier–Amery Ice
Shelf region of East Antarctica. Comparisons with both existing flow-direction fields and traced
streamlines over the same area provide an evaluation of the method. We also illustrate its application to
Landsat 7 imagery.
