Ice Cover Delineation Over Devon Iceland Using Sentinel Polarimetric SAR and Optical Data ...
Accurate information on the extent and dynamics of ice cover is important on a global scale. Owing to the daynight and weather-independent imagery capabilities, Sentinel-1 (S1) is a reliable source for ice monitoring using synthetic aperture radar (SAR) images. Therefore, this study focuses on an un...
