Abstract
SI-STSAR-7 is a labeled spatiotemporal dataset for sea ice classification based on SAR images. The dataset is produced from 80 Sentinel-1 A/B SAR scenes during the two freezing periods of Hudson Bay from October 2019 to May 2020 and from October 2020 to April 2021, which are provided by the Copernicus Open Access Center. The Sentinel-1 SAR images were preprocessed with noise reduction and incidence angle dependence correction before use.
The dataset includes 7 classes including Open Water (OW), New ice (NI), Grey ice (GI), Grey White ice (GWI), Thin First year ice (ThinFI), Medium First year ice (MedFI) and Thick First year ice (ThickFI). We referenced the weekly regional ice map provided by the Canadian Ice Service for sea ice class labeling. Each data sample is a SAR image block that contains dual-polarization (HH and HV) SAR data with a spatial resolution 32x32 and a time step 6 (that is derived from 6 consecutive SAR scenes).
