Landsat-8 Sea Ice Classification Using Deep Neural Networks
Abstract: Knowing the location and type of sea ice is essential for safe navigation and route op-timization in ice-covered areas. In this study, we developed a deep neural network (DNN) for pixel-based ice Stage of Development classification for the Baltic Sea using Landsat-8 optical sat-ellite imag...
