Abstract:
This dataset contains binary maps of ice (1) and open water (0) in Hornsund fjord, Svalbard at 50 m resolution. The maps are based on the Sentinel-1A/B Synthetic Aperture Radar (SAR) archive between 14.10.2014 and 29.06.2023 with an average image frequency of 1.57 days. An algorithm was run on the radar backscatter and incidence angle images to divide fjord into typically 5 discontinuous segments, which were then classified as either ice or open water. A document containing details on the scenes and polarisation channels used, the number of segments and the level of manual editing is provided.
