I have resampled my S2B, L2A image, cropped it, and collected vector samples of several land cover features to train and classify my subset. However, the result is blank output. Interestingly, class evaluation report entails assessment statistics of input classes. I tried RF and Maximum Liklihood classifiers and encountered same blank raster each time. I have consulted documentation as well as a YouTube tutorial to cross check. Nothing found skeptical. All of processing steps mimic the demonstration.
I’m using current version of SNAP on Windows 10.
