So2Sat

So2Sat is a local climate zone (LCZ) classification task consisting of images from Sentinel-1 and Sentinel-2. We only keep Sentinel-2 images which have 10 MSI bands in this dataset. In addition, we reserve 10% of the training set as the validation set, resulting in 31,713 training samples, 3,523 validation samples and 48,307 test samples.
