Semantic Sea-Ice Classification for Belgica Bank in Greenland

Dumitru Octavian; Karmakar Chandrabali; Datcu Mihai

Each Sentinel-1 image is tiled into patches of 256x256 pixels. The size of the images is different and we reduced to the smallest one. In total for each image are 6,400 patches [1-2, 4]. See the excel file for the 24 Sentinel-1 ids.

The semantic classes are:

  1. Black border
  2. Old ice
  3. First-Year ice
  4. Glaciers
  5. Icebergs
  6. Mountains
  7. Young ice
  8. Water group

The last class combines the Floating ice, Water body, Water ice current and melted snow defined in [3] because they have very similar physical properties.
