Tracking dynamic sea-ice process with RADARSAT-2 imagery

To monitor dynamic changes in sea ice using SAR (Synthetic Aperture Radar) imagery in polar regions, we propose an object-oriented regional segmentation and dynamic object identification method that discriminates between sea ice and open water, classifies sea ice into different types, identifies sea-ice objects, and detects and represents dynamic changes. As a case study, the method was applied to RADARSAT-2 SAR imagery with standard ScanSAR mode covering the Arctic region, acquired on August 13, 15 and 17 in 2010. The results demonstrate the validity and feasibility of the proposed method.
