Lake Ice Classification from Sentinel-1A 2015 - 2018
In the ESA DUE GlobPermafrost project lake ice classifications were produced to distinguish grounded ice and floating ice in lakes in Barrow (Arctic Alaska, US), Teshekpuk (Arctic Alaska, US), Mackenzie Delta (Beaufort Sea Region, CA), Kytalyk (Central Yakutia, RU), Lena Delta (Laptev and East Siber...
