Ice sheet margin detection using ERS-1 synthetic aperture radar

A portion of the Greenland ice sheet margin near the Jakobshavn area is mapped using an automatic, hierarchical approach applied to ERS-1 synthetic aperture radar (SAR). Image tone and texture variability between the bare ice facies near the ice sheet margin and recently deglaciated rocks are used to map the ice sheet margin. This process involves integration of an anisotropic diffusion algorithm, local dynamic thresholding method, and edge following scheme.
