Using deep learning for feature extraction and classification For a human, it's relatively easy to understand what's in an image—it's simple to find an object, like a car or a face; to classify a structure as damaged or undamaged; or to visually identify different land cover types. For machines, the task is much more difficult. However, it's critical to be able to use and automate machine. The dataset contained 27,000 64×64 images with 13 spectral bands which were classified into 10 generic land cover types (Highway, Industrial, Residential, Pasture, Forest, Herbaceous Vegetation, Sea Lake, River, Permanent Crop and Annual Crop). You can find Sentinel-2 sensor specifications here.
