Ice Cover Delineation Over Devon Iceland Using Sentinel Polarimetric SAR and Optical Data
The accurate extraction of ice cover is important on a global scale. Owing to the weather-independent imagery capabilities, Sentinel-1 (S1) is a reliable source for ice cover monitoring using SAR images. Therefore, this study focused on an unsupervised method for extracting ice cover by exploiting d...

The accurate extraction of ice cover is important on a global scale. Owing to the weather-independent imagery capabilities, Sentinel-1 (S1) is a reliable source for ice cover monitoring using SAR images. Therefore, this study focused on an unsupervised method for extracting ice cover by exploiting dual-pol S1 SAR data over Devon Island, which is surrounded by the ocean. We adopted a constant false alarm rate (CFAR) detector for ice cover detection by examining the empirical distribution of a given matrix over an ice region followed by a statistical Burr distribution to derive the CFAR threshold value. To detect ice cover, a binary image was first retrieved, and then the ice edges were quantified using a Canny edge detector. To evaluate the effectiveness of the proposed method, we applied it to SAR data from a challenging environment, including the terrain, ice, and ocean. The accuracy of the proposed dual-pol matrix and the SOA single-pol matrix were meticulously compared with the S2 data (ground-truth reference). Quantitative findings demonstrate the validity of the proposed method for ice cover extraction using Sentinel-1 data. Finally, retreat velocity estimation is important for meteorological pursuits. |
