I am performing land cover land use classification using Sentinel 1 and Sentinel 2 data. Since, in Sentinel 1 (SAR) data, the classes cannot be differentiated visibly, I need a way to develop the training dataset with labelled classes. Is there any website available where training dataset is available? I have already download the Sentinel 1 and Sentinel 2 data from ESA Copernicus hub. Thank you.
